how many sources of variance are found in a 3 x 3 between subjects factorial design?

Answers

Answer 1

In a 3 x 3 between subjects factorial design, there are four sources of variance.

A 3 x 3 between subjects factorial design involves two independent variables, each with three levels, and participants are randomly assigned to different combinations of these levels. In this design, the four sources of variance are as follows:

Main Effect of Variable A: This source of variance represents the overall effect of the levels of the first independent variable. It assesses whether there are significant differences between the means of the three groups created by varying levels of Variable A.

Main Effect of Variable B: This source of variance represents the overall effect of the levels of the second independent variable. It examines whether there are significant differences between the means of the three groups created by varying levels of Variable B.

Interaction Effect: This source of variance assesses whether there is an interaction between the two independent variables. It examines whether the effect of one independent variable on the dependent variable differs across the levels of the other independent variable.

It evaluates whether the combined effect of the independent variables is greater (or lesser) than the sum of their individual effects.

Error Variance: This source of variance represents the variability in the dependent variable that cannot be accounted for by the independent variables. It includes random error, individual differences, and any other uncontrolled factors that may influence the outcome.

Therefore, in a 3 x 3 between subjects factorial design, there are four sources of variance: the main effects of Variable A and Variable B, the interaction effect between the two variables, and the error variance.

Each of these sources contributes to understanding the overall pattern of results and the relationships between the variables in the design.

What is the average rate of change for this function for the interval from x = 1
to x = 3?

Answers

Answer:

Step-by-step explanation:

To find the average rate of change for an exponential function over an interval, we can use the formula:

average rate of change = (f(b) - f(a)) / (b - a)

where “a” and “b” are the endpoints of the interval, and “f” is the exponential function.

In this case, the interval is from x = 1 to x = 3, so a = 1 and b = 3. We are given the values of the function for these inputs:

f(1) = 7

f(2) = 9

f(3) = 13

Substituting these values into the formula, we get:

average rate of change = (f(3) - f(1)) / (3 - 1)

average rate of change = (13 - 7) / 2

average rate of change = 3

Therefore, the average rate of change for this function over the interval from x = 1 to x = 3 is 3.

B) x ≤ 16.5
C) x ≥ 34
D) x ≥ 16 5

Answers

The expression that represents the perimeter of the triangle is 5x - 2.

Writing an expression

From the question, we are to write an expression that represents the perimeter of the triangle

From the given information,

"The length of the base of the triangle is represented by x"

and

"The legs are 1 unit less than twice the length of the base"

∴ One leg of the triangle = 2x - 1

The perimeter of a rectangle is the sum of all the sides

Thus,

Perimeter of the isosceles triangle = 2x - 1 + 2x - 1 + x

Perimeter of the isosceles triangle = 2x +2x + x - 1 - 1

Perimeter of the isosceles triangle = 5x - 2

© d < 5
D d > 5

Answers

Answer:

The answer to your question is B) d≥ 5 because the best inequality that represents the number of days Amaya practices the guitar is "greater than or equal to 5". This is because Amaya practices the guitar at least 5 days a week, so the inequality that represents this would be d≥ 5.

Answer:

B

Step-by-step explanation:

Based on the given number line, we can see that the number of days Amaya practices the guitar falls on and to the right of the number 5. Since the number line is inclusive of 5, it means that Amaya practices for 5 days or more in a week.

Therefore, the inequality that BEST represents the number of days, d, she practices is:

B) d ≥ 5

This inequality indicates that the number of days Amaya practices (d) is greater than or equal to 5.

find the indefinite integral and check the result by differentiation. (use c for the constant of integration.) 5x /(5 − x^2)^3

Answers

The indefinite integral of 5x /(5 − x^2) ^3 is (5 − x^2) ^−2 + C, where C is the constant of integration. The indefinite integral of 5x / (5 − x^2) ^3 can be found by using the substitution u = 5 − x^2. We have:

∫ 5x / (5 − x^2) ^3 dx

Let u = 5 − x^2, then du/dx = −2x and dx = −(1/2x) du. Making the substitution, we get:

∫ 5x /(5 − x^2) ^3 dx = ∫ (−1/2) (−2x) u^−3 du

= u^−2 + C, where C is the constant of integration.

Substituting back, we get:

∫ 5x / (5 − x^2) ^3 dx = (5 − x^2) ^−2 + C

To check the result by differentiation, we take the derivative of (5 − x^2) ^−2 + C with respect to x:

d/dx [(5 − x^2) ^−2 + C] = −2(5 − x^2) ^−3 (−2x) = 4x / (5 − x^2) ^3

Which is the original function. Hence, our result is correct.

In conclusion, the indefinite integral of 5x / (5 − x^2) ^3 is (5 − x^2) ^−2 + C, where C is the constant of integration. This can be checked by taking the derivative of the result and verifying that it gives us the original function.

if the assumption for using the chi-square statistic that specifies the number of frequencies in each category is violated, the researcher can: group of answer choices obtain a larger sample and collapse some categories are both correct choose a different statistical test obtain a larger sample collapse some categories

Answers

If the assumption for using the chi-square statistic that specifies the number of frequencies in each category is violated, the researcher can take a couple of steps to address the issue.

First, they can obtain a larger sample, which may help to achieve a better distribution of frequencies across the categories. This can improve the reliability and validity of the chi-square test.
Additionally, the researcher can collapse some categories to ensure that each one has a sufficient number of observations. By combining similar categories, the chi-square test's assumptions may be better satisfied, leading to more accurate conclusions.
If obtaining a larger sample or collapsing categories does not resolve the issue, the researcher might consider choosing a different statistical test that is more appropriate for their data and research question. This alternative test should be carefully selected based on the study's design, the type of data being analyzed, and the specific research objectives.
In summary, when the assumptions for using the chi-square statistic are violated, researchers can take several steps to address the issue: obtain a larger sample, collapse some categories, or choose a different statistical test. Each approach has its merits, and researchers should carefully evaluate their options to ensure the most accurate and meaningful conclusions are drawn from their data.

There were 40 more children than adults in a cinema. If the adults paid 50 naria each, the children 30 naria each, and the total amount paid altogether was 41200 naria. Find the total number of people in the cinema

Answers

Let's assume that the number of adults in the cinema is x. Since there were 40 more children than adults, the number of children would be x + 40.

The total amount paid altogether was 41200 naria, which means that the amount paid by the adults would be 50x and the amount paid by the children would be 30(x+40).

To find the total number of people in the cinema, we need to solve for x. We can start by simplifying the equation:

50x + 30(x+40) = 41200

80x + 1200 = 41200

80x = 40000

x = 500

Therefore, there were 500 adults and 540 children in the cinema, making the total number of people in the cinema 1040.

Step-by-step explanation:

Use your knowledge of patterns to find how high a stack of chairs will be that has 8 chairs in it. 1.5.1 Write down the constant difference 1.5.2 Using the general rule, determine how many chairs would there be if the stack was 127cm high?​

Answers

Answer:

1.5.1 : constant difference is 8

1.5.2: When there are 10 chairs stacked, it's 127 cm tall.

Step-by-step explanation:

There is a linear relationship between the height of the stack and the number of chairs.

1 chair = 55 cm + 0 extra cm = 55cm

2 chairs = 55cm + 8cm = 63 cm

3 chairs = 55cm + 8(2)cm = 71 cm

4 chairs = 55cm + 8(3)cm = 79 cm

1.5.1 the constant difference between all the underlined numbers above is 8.

1.5.2 You could just keep calculating above until you get 127 cm. (Your teacher might not like that, but it's an option!)

You can find the equation & either solve for the number of chairs OR graph it.

So if we let C = the number of stacked chairs, our equation for H (height) would be:

H = 55 + 8(C-1)

If we substitute H = 127, solve for C.

127 = 55+ 8(c-1)

127 = 55+ 8c-8

127 = 47 + 8c

127 -47 = 8c

80 = 8c

10=c

When there are 10 chairs stacked, it's 127 cm tall.

Check that the answer works:

55 cm (1st chair) + 8*9 (8cm for each additional chair) = 55+ 72 = 127 cm

The Lagrange form of the polynomial that fits the given data is L(x) = (1/4)*x^3 - (3/2)*x^2 + (17/4)*x - 3.

To find the Lagrange form of the polynomial that fits the given data, we can use the following formula:

Lagrange form:

L(x) = ∑ [y * l_i(x)], i=0 to n

where

l_i(x) = ∏ [(x - x_j)/(x_i - x_j)], j=0 to n, j ≠ i

In this formula, x and y are the given data points, n is the number of data points (n+1 is the degree of the polynomial), and L(x) is the polynomial that fits the data.

Using the given data x = {1, 2, 3, 5} and y = {0, 5, 26, 164}, we can compute the Lagrange form as follows:

l_0(x) = (x - 2)(x - 3)(x - 5)/(1 - 2)(1 - 3)(1 - 5) = -(x^3 - 10x^2 + 31x - 30)/4
l_1(x) = (x - 1)(x - 3)(x - 5)/(2 - 1)(2 - 3)(2 - 5) = (x^3 - 9x^2 + 23x - 15)/2
l_2(x) = (x - 1)(x - 2)(x - 5)/(3 - 1)(3 - 2)(3 - 5) = -(x^3 - 8x^2 + 13x - 6)/2
l_3(x) = (x - 1)(x - 2)(x - 3)/(5 - 1)(5 - 2)(5 - 3) = (x^3 - 6x^2 + 11x - 6)/4

L(x) = 0l_0(x) + 5l_1(x) + 26l_2(x) + 164l_3(x)
= (1/4)*x^3 - (3/2)*x^2 + (17/4)*x - 3

Answers

To construct a confidence interval, we need to determine the critical value based on the confidence level and sample size. For a 95% confidence level and a sample size of 7, the critical value is 2.571.

The critical value is used to calculate the margin of error for a confidence interval. It is based on the confidence level and sample size, and it is determined from a t-distribution table or a calculator.

For a 95% confidence level and a sample size of 7, we can find the critical value by looking at the t-distribution table with 6 degrees of freedom (df = n - 1). The 95% confidence level corresponds to a two-tailed test with an alpha level of 0.05, and the critical value for a t-distribution with 6 degrees of freedom and an alpha level of 0.025 (half of 0.05) is 2.571.

Therefore, to construct a 95% confidence interval for a sample size of 7, we can use the formula:

sample mean ± (critical value) x (standard error of the mean)

where the standard error of the mean is calculated as the sample standard deviation divided by the square root of the sample size.

in rolling 2 fair dice what is the probability of a sum greater than 3 but not exceeding 6

Answers

We can list all possible outcomes in a table and count the number of outcomes that meet the criteria. There are 9 such outcomes, which gives a probability of 9/36, or 1/4.

To calculate the probability of rolling a sum greater than 3 but not exceeding 6 with 2 fair dice, we first need to determine the total number of possible outcomes when rolling the dice. Since each die has 6 possible outcomes, there are a total of 6 x 6 = 36 possible outcomes when rolling 2 fair dice.

| Die 1 | Die 2 | Sum |

| 3     | 2     | 5   |
| 4     | 1     | 5   |
| 5     | 1     | 6   |

There are a total of 9 outcomes where the sum is greater than 3 but not exceeding 6. Therefore, the probability of rolling a sum greater than 3 but not exceeding 6 with 2 fair dice is 9/36, which simplifies to 1/4.
The probability of rolling a sum greater than 3 but not exceeding 6 with 2 fair dice can be calculated by dividing the number of outcomes where the sum is greater than 3 but not exceeding 6 by the total number of possible outcomes.

There are a total of 36 possible outcomes when rolling 2 fair dice, as each die has 6 possible outcomes. To determine the number of outcomes where the sum is greater than 3 but not exceeding 6, we can list all possible outcomes in a table and count the number of outcomes that meet the criteria.

where Z-score is the critical value for the level of confidence (in this case, 95%), σ is the population standard deviation (which is equal to the square root of the variance, so σ = 12), and n is the sample size.

We want the margin of error to be less than or equal to 5, so we can set up the following inequality:
5 ≥ Z-score * (σ / √n)

To find the value of the Z-score for 95% confidence, we can use a standard normal distribution table or calculator. The Z-score for 95% confidence is approximately 1.96.

Substituting the values we have into the inequality, we get:
5 ≥ 1.96 * (12 / √n)

Solving for n, we get:
n ≥ ((1.96 * 12) / 5)²
n ≥ 138.2976

Since we cannot have a fractional sample size, we need to round up to the nearest whole number:
n = 139

Therefore, a sample size of at least 139 should be taken to ensure that the margin of error does not exceed 5, with a population variance of 144 and a 95% confidence level.

In summary, the long answer to your question is that we used the formula for the margin of error, substituted the given values, solved for n, and rounded up to get a sample size of 139.

What are equivalent exponents?

Equivalent exponents are any two or more exponents that, when added to a base number, produce the same value or result. In other words, equivalent exponents are various ways of expressing the same exponentiation-based mathematical action.

We now have that;

[tex](49^2/5) (7^- 3/4)\\(7^2)^2/5 (7^-3/4)\\(7^4/5) (7^-3/4)\\7^ (4/5 - 3/4)\\7^ 1/20[/tex]

for a two-tailed hypothesis test with a sample size of 37 and a 0.10 level of significance, what are the critical values of the test statistic t?

Answers

For a two-tailed hypothesis test with a sample size of 37 and a 0.10 level of significance, the critical values of the test statistic t are approximately ±1.691. These values determine whether we reject or fail to reject the null hypothesis based on the calculated t-value.

To find the critical values of the test statistic t for a two-tailed hypothesis test, we need to use the t-distribution table or statistical software. The critical values of t depend on the level of significance and the degrees of freedom (df), which are calculated as n-1, where n is the sample size.

For a two-tailed test with a level of significance of 0.10 and 37 degrees of freedom, we need to find the t-value that cuts off 0.05 of the area in each tail of the t-distribution. Using a t-distribution table or software, we find that the critical values of t are approximately ±1.691.

This means that if the calculated t-value falls outside the range of ±1.691, we reject the null hypothesis at the 0.10 level of significance, and conclude that there is significant evidence to support the alternative hypothesis. If the calculated t-value falls within the range of ±1.691, we fail to reject the null hypothesis and conclude that there is not enough evidence to support the alternative hypothesis.

It is important to note that the critical values of t depend on the sample size and the level of significance. As the sample size increases, the degrees of freedom increase and the t-distribution approaches the normal distribution. Also, as the level of significance decreases, the critical values of t become more extreme, making it harder to reject the null hypothesis.

Companies X and Y have been offered the following rates per annum on a $5 million 10 -year investment: Company X requires a fixed-rate investment; company Y requires a floating-rate investment. A. Assuming X and Y split the gains from the swap in such a way that X gets 60% of the gains and Y gets 40% of the gains, what are the net investment rates that X and Y can get? B. If a Financial Intermediary (FI) charges 0.2% a year (split equally between X and Y ), how would this affect the final rates that the two parties are receiving? C. Illustrate the swap between X and Y in the presence of a financial intermediary with the help of a diagram. Please make sure that all rates are properly labeled.

Answers

A. X receives a net investment rate of 6% and Y receives a net investment rate of 4%.

B. X receives a final net investment rate of 5.8% and Y receives a final net investment rate of 3.8%.

C.  X: 5.8%, Y: 3.8%

A. Assuming X and Y split the gains from the swap in such a way that X gets 60% of the gains and Y gets 40% of the gains, the net investment rates that X and Y can get is as follows:

X: 5,000,000 x 0.06 = 300,000

Y: 5,000,000 x 0.04 = 200,000

Therefore, X receives a net investment rate of 6% and Y receives a net investment rate of 4%.

B. If a Financial Intermediary (FI) charges 0.2% a year (split equally between X and Y), the final rates that the two parties are receiving is as follows:

X: 5,000,000 x (0.06 - 0.002) = 298,000

Y: 5,000,000 x (0.04 - 0.002) = 198,000

Therefore, X receives a final net investment rate of 5.8% and Y receives a final net investment rate of 3.8%.

C. The swap between X and Y in the presence of a financial intermediary can be illustrated in the following diagram:

X: 5,000,000 x 0.06 = 300,000

Y: 5,000,000 x 0.04 = 200,000

FI: 0.2% (split equally between X and Y)

X: 5,000,000 x (0.06 - 0.002) = 298,000

Y: 5,000,000 x (0.04 - 0.002) = 198,000

X: 5.8%

Y: 3.8%
