Based on the mentioned informations, the farmer is calculated to have 143 chickens left after selling 2/5 and 5/6 of the initial 1800 chickens and 37 chickens died.

The farmer starts with 1800 chickens.

He sells 2/5 of the total, which is:

(2/5) x 1800 = 720 chickens.

So he has 1080 chickens left.

He then sells 5/6 of the remaining chickens, which is:

(5/6) x 1080 = 900 chickens.

So he has 180 chickens left.

Unfortunately, 37 chickens die, so the final number of chickens he has left is:

180 - 37 = 143 chickens.

Therefore, the farmer has 143 chickens left after selling 2/5 and 5/6 of the initial 1800 chickens and 37 chickens died.

The hypothesis test would give a binary answer of whether or not the proportions are significantly different, while the confidence interval estimate would provide a range of plausible values for P1.

The null hypothesis for the hypothesis test is that the proportion of people with the common attribute in the first population (P1) is equal to the proportion of people with the common attribute in the second population (P2). The alternative hypothesis is that P1 is not equal to P2.

When conducting the hypothesis test with a 0.01 significance level, we would calculate the test statistic and compare it to the critical value from a t-distribution with degrees of freedom equal to the sum of the sample sizes minus two. If the test statistic falls outside of the critical region, we would reject the null hypothesis and conclude that the proportions are significantly different.

On the other hand, the 99% confidence interval estimate of p would provide a range of values that P1 could fall within with 99% confidence. We would calculate the confidence interval by taking the difference in proportions (P2 - P1) and adding/subtracting the margin of error, which is based on the sample sizes and the level of confidence desired.

Overall, comparing the results from the hypothesis test and the confidence interval estimate would provide different information about the proportions in the two populations.

The equation of the line in point slope form and slope intercept form are y + 4 = -10 (x + 5) and y = -10x - 19 respectively.

Given that,

A line passes through the point (-5, -4) and the slope is -10.

The equation of the line in point slope form can be written as,

y - y' = m(x - x')

where m is the slope and (x', y') is the point on the line.

Substituting,

y - -4 = -10(x - -5)

y + 4 = -10 (x + 5), which is the point slope form.

Simplifying,

y + 4 = -10x - 15

(a) The answer of the question "What is the interval's margin of error (Round your answers to 3 decimal places.)" to part (b) is B = 0.978.

(b) margin of error = 1.96*(10/sqrt(385)) = 0.978

(a) To find the sample size needed to construct a 95% confidence interval with a margin of error of 1, we use the formula:

margin of error = z*(standard deviation/sqrt(sample size))

where z is the critical value from the standard normal distribution for a 95% confidence level, which is approximately 1.96.

Plugging in the given values and solving for the sample size, we get:

[tex]1 = 1.96*(10/sqrt(sample size))[/tex]

[tex]sqrt(sample size) = 1.96*10/1[/tex]

[tex]sample size = (1.96*10)^2 = 384.16[/tex]

Rounding up to the nearest whole number, we need a sample size of 385.

Therefore, the answer to part (a) is 385.

(b) To calculate the 95% confidence interval for the population mean given a sample size of 385 and a sample mean of 295, we use the same formula as above with the values we have:

1 = 1.96*(10/sqrt(385))

Solving for the margin of error, we get:

margin of error = 1.96*(10/sqrt(385)) = 0.978

The 95% confidence interval for the population mean is then:

295 - 0.978 to 295 + 0.978

or

(294.022, 295.978)

Therefore, the answer to part (b) is B = 0.978.

Stochastic simulations use random variables or probability distributions to model uncertainty in the system being simulated.

The type of simulation that is defined over a theoretically infinite time frame is called a "steady-state simulation".

In a steady-state simulation, the system being modeled is assumed to have reached a stable state where the behavior of the system does not change over time. The simulation is then run for a long period of time, allowing the outputs to converge to a steady state. The quantities to be estimated are defined over this theoretically infinite time frame.

On the other hand, terminating simulations have a fixed end time, and the simulation is terminated when that time is reached.

The test statistic is z = 2.75. Since the test statistic is greater than 1.96, we reject the null hypothesis and conclude that the proportion of the population in favor of candidate a is significantly more than 70%.

To calculate the test statistic, we first need to find the proportion of the sample that favored candidate a:
Proportion = 80/111 = 0.72
Next, we calculate the standard error of the proportion:
SE = sqrt[(0.7)(0.3)/111] = 0.045
Finally, we calculate the test statistic using the formula:
z = (Proportion - Hypothesized Proportion) / SE
z = (0.72 - 0.7) / 0.045 = 2.75
Since the test statistic is greater than 1.96 (the critical value for a two-tailed test at the 5% level of significance), we reject the null hypothesis and conclude that the proportion of the population in favor of candidate a is significantly more than 70%.

To determine whether the proportion of the population in favor of candidate A is significantly more than 70%, we'll use the test statistic formula for proportions:
Test statistic = (Sample proportion - Hypothesized proportion) / Standard error
In this case, a random sample of 111 people was taken, and 80 of them favored candidate A. We are interested in finding if the proportion favoring candidate A is more than 70% (0.7).
First, calculate the sample proportion:
Sample proportion = Favored candidate / Total sample
Sample proportion = 80 / 111 ≈ 0.7207
Next, calculate the standard error using the formula:
Standard error = √(p(1-p)/n), where p is the hypothesized proportion and n is the sample size.
Standard error = √(0.7 * (1-0.7) / 111) ≈ 0.0452
Finally, calculate the test statistic:
Test statistic = (0.7207 - 0.7) / 0.0452 ≈ 0.4581
The test statistic for determining whether the proportion of the population in favor of candidate A is significantly more than 70% is approximately 0.4581.

The correct answer is c. Yes, because the evidence was not strong enough to suggest that average reading and writing scores differ.

In hypothesis testing, we use a significance level to determine whether to reject or fail to reject the null hypothesis. If the p-value is less than the significance level, we reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis. If the p-value is greater than the significance level, we fail to reject the null hypothesis and conclude that there is not enough evidence to support the alternative hypothesis.

Based on the results of the hypothesis test, if we failed to reject the null hypothesis (which is the case in this question), then we cannot conclude that the average reading and writing scores differ. Therefore, it is reasonable to expect a confidence interval for the average difference between the reading and writing scores to include 0. A confidence interval is a range of values that is likely to contain the true population parameter with a certain degree of confidence. Since we cannot conclude that the average scores differ, it is possible that the true population parameter is 0, and thus 0 could be included in the confidence interval.

The correct answer is e) no, it is not a function because it does not pass the horizontal line test.

A function must have only one output for every input, and the horizontal line test checks for this by seeing if any horizontal line intersects the graph more than once. This graph has multiple points where a horizontal line would intersect it more than once, indicating that it does not represent a function. The fact that it contains a quadratic and linear relation or has two open circles is not relevant to determining whether it is a function or not.
C) Yes, it is a function because it passes the vertical line test.

A graph represents a function if and only if it passes the vertical line test. This means that for any given x-value, there is only one corresponding y-value. The horizontal line test is used to determine if a function has an inverse that is also a function, which is not relevant to this question.

To solve this problem, we need to use the Principle of Inclusion-Exclusion (PIE). Let A be the set of all quadruplets (a1,a2,a3,a4) of non-negative integers that satisfy the equation a1+a2+a3+a4=100, and let B be the set of all quadruplets where all four integers are odd. Then the number of quadruplets that satisfy the given condition is given by:

To find |A|, we can use stars and bars. If we consider 100 stars and 3 bars, we can partition the stars into 4 groups, corresponding to the four integers. There will be 99 gaps between the stars and bars, and we need to choose 3 of them to place the bars. This gives us:
|A| = (99 choose 3) = 161,700
To find |B|, we can use a similar approach. If all four integers are odd, then they must be of the form 2k+1, where k is a non-negative integer. Substituting this into the equation a1+a2+a3+a4=100, we get:
2k1 + 1 + 2k2 + 1 + 2k3 + 1 + 2k4 + 1 = 100
Simplifying this equation, we get:
k1 + k2 + k3 + k4 = 48
