Suppose you draw a sample of size 5 where each observation comes from a Bernoullidistribution with probability of success equal to 0.4.When answering the questions below, make sure to explain your answers (showhow you got the answers). More than half of the points for each question areallocated to your explanations. Keep 4 digits after the period for all questions (e.g.2.4505).a) Develop the sampling distribution for the sample mean in this case. Use a table andshow your work.b) What is the standard error for this sampling distribution? Show your work.

The large airline company, Tale Winds, knows from experience that only 77% of the passengers booked for flights actually show up. Suppose that we will take a random sample of 8 Tale Winds passengers. Let p represent the proportion of passengers from the sample who show up for their flight. Consider the sampling distribution of the sample proportion p . Complete the following. Carry your intermediate computations to four or more decimal places. Write your answers with two decimal places, rounding if needed. (a) Find un (the mean of the sampling distribution of the sample proportion). HA = ] (b) Find oA (the standard deviation of the sampling distribution of the sample proportion). ?

A sampling distribution (dotplot) for the mean quiz score for a sample n = 30 of STAT101 students is shown below. It was constructed using random samples from population data. If we increased our sample size from 30 to 100, would the standard error of the sample mean be larger, smaller, or the same? Explain your answer in one or two sentences.
Describe the sampling distribution of p. Assume the size of the population is 20,000. n= 900, p = 0.6 ..... Choose the phrase that best describes the shape of the sampling distribution of p below. O A. Not normal because ns0.05N and np(1 - p) 10. Determine the mean of the sampling distribution of p. Ha = (Round to one decimal place as needed.) Determine the standard deviation of the sampling distribution of p. (Round to three decimal places as needed.)
Let's examine the mean of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 by drawing samples from these values, calculating the mean of each sample, and then considering the sampling distribution of the mean. To do this, suppose you perform an experiment in which you roll an eight-sided die two times (or equivalently, roll two eight-sided dice one time) and calculate the mean of your sample. Remember that your population is the numbers 1, 2, 3, 4, 5, 6, 7, and 8. The true mean (µ) of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 is , and the true standard deviation (o) is The number of possible different samples (each of size n = 2) is the number of possibilities on the first roll (8) times the number of possibilities on the second roll (also 8), or 8(8) = 64. If you collected all of these possible samples, the mean of your sampling distribution of means (µM) would equal and the standard deviation of your sampling distribution of means (that is, the standard error or ɑm) would be The following chart…
Determine whether the statement is true or false. If it is false, rewrite it as a true statement. A sampling distribution of a sample mean is normal only if the population is normal. Choose the correct answer below. O A. The statement is false. A sampling distribution of a sample mean is approximately normal if either n ≥ 30 or the population is normal. B. The statement is false. A sampling distribution of a sample mean is never normal. O C. The statement is false. A sampling distribution of a sample mean is approximately normal only if n ≥ 30. OD. The statement is true.
