What is the precent of increase from 5 to 6?

Answer:

1)

Null hypothesis            H₀ : μ = 25,809

Alternative hypothesis H₁ : μ < 25,809

2) Test Statistic = -1.44

3) Conclusion:

The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

Step-by-step explanation:

Given the data in the question;

Sample mean x" = 24,638

sample size n = 46

standard deviation σ = 5531

level of significance ∝ = 0.10

NULL and ALTERNATIVE HYPOTHESIS

Null hypothesis            H₀ : μ = 25,809

Alternative hypothesis H₁ : μ < 25,809

TEST STATISTICS

Z = (x"-μ) / σ√n

we substitute

Z = (24,638 - 25,809) / (5531/√46)

Z = -1171 / 815.5

Z = -1.44

Test Statistic = -1.44

Now, from normal z-table;

P-value = P( Z < -1.44 ) = 0.0749

P-value = 0.0749

Since P-value ( 0.0749 ) is less than level of significance ( 0.10 ), we reject H₀.

Conclusion:

The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

For the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.

Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.

Lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.

Similarly, second quartile (also called median) is approximately in mid of the data.

Third quartile (also called upper quartile)  has approx 75% in its left partition, and on its right lies approx 25% of the data.

Left to right is said in assumption that data was arranged increasingly from left to right

For this case, it is said that 25% of the class weighted less than 6 pounds 1 ounce. That means it is first quartile or say lower quartile.

Thus, for the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

Answer:

The 99.5% confidence interval for the mean price for all phones of this type being sold on the Internet in 2013 is between $140.39 and $309.11

Step-by-step explanation:

Sample mean:

Sum of all values divided by the number of values. So

[tex]S_{m} = \frac{249+349+299+249+149+135+199+169}{8} = 224.75[/tex]

Confidence interval:

We have the standard deviation for the population, so the z-distribution is used.

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.995}{2} = 0.0025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.0025 = 0.9975[/tex], so Z = 2.807.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.807\frac{85}{\sqrt{8}} = 84.36[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 224.75 - 84.36 = $140.39

The upper end of the interval is the sample mean added to M. So it is 224.75 + 84.36 = $309.11

The 99.5% confidence interval for the mean price for all phones of this type being sold on the Internet in 2013 is between $140.39 and $309.11

Answer:

16.25 mL

Step-by-step explanation:

Since we are mixing from the syrup in the inventory, we can say that the syrup in the inventory must be equal to that in the final solution. Thus, we will use the dilution equation to solve for the Initial volume;

Dilution equation is;

V₁C₁ = V₂C₂

Where;

V₁ is initial volume

C₁ is initial concentration or initial molarity

V₂ is final volume

C₂ is final concentration of final molarity

We are given;

C₁ = 80% = 0.8

C₂ = 60% = 0.6

V₂ = 65 mL

Making V₁ the subject in the dilution equation, we have;

V₁ = (V₂C₂)/C₁

V₁ = (65 × 0.6)/0.8

V₁ = 48.75 mL of inventory syrup

Since we have 48.75 mL of inventory syrup and the dilute solution is 65 ml, then the volume of soda solution required = 65mL - 48.75 mL = 16.25 mL

Answer:

7.5

Step-by-step explanation:

Answer:

197 adult tickets and 354 child tickets were sold for the event.

Step-by-step explanation:

Given that the Family Fine Arts Center charges $ 22 per adult and $ 14 per child under 12 years old for its performances, and on a recent weekend evening when 551 people paid admission, the total receipts were $ 9290, to determine how many who paid were children under 12 years old the following calculation must be performed:

22 - 14 = 8

551 x 14 = 7.714

9,290 - 7,714 = 1,576

1,576 / 8 = 197

551 - 197 = 354

197 x 22 + 354 x 14 = X

4.334 + 4.956 = X

Therefore, 197 adult tickets and 354 child tickets were sold for the event.

Answer:

area = 24 units squared

Step-by-step explanation:

area = 1/2 (base 1 + base 2) x height

area = 1/2 (12) x 4

area = 6 x 4

area = 24

Answer:

n = 1/2 or .5

Step-by-step explanation:

4n + 3 = 10 -10n

14n = 7

n = 1/2 or .5

Hope this helps!

Answer:

n = -0.5

Step-by-step explanation:

4n + 3 = 5(2 - 2n)

First you multiply 2 and 2n by 5

4n + 3 = 10 - 10n

subtract 4n on both sides (meaning subtract 4n by itself on the left side of the equal sign and subtract 10n and 4n)

3 = 10 + 14n

Subtract 10 on both sides

-7 = 14n

Divide on both sides

Your answer should be n = -0.5 (or -0.5 = n)

Hope this helps!
