Given a population of class sizes at a university in an academic year, indicate what the sampling distribution for samples of 20 would consist of.Choose the correct answer below.A. The sampling distribution is a representative collection of 20 samples, each containing 20 class sizes, selected with replacement.B. The sampling distribution is a representative collection of 20 samples, each containing 20 class sizes, selected without replacement.C.

Race organizers want to survey the participating runners on the quality of the running course. Which of the following uses systematic random sampling? Select the first 15 finishers and the last 15 finishers to take the survey. Randomly select 15% of the male participants and 15% of the female participants. Select the 5th finisher (with the number 5 being randomly chosen) to survey, then survey every 15th finisher after that. Sort all of the runners' names alphabetically, then randomly choose 2 letters and survey all participants whose last name begins with one of those letters.

A quarterback threw 1 interception in his first game, 2 interceptions in his second game, and 5 inter-ceptions in his third game, and then he retired. Consider the values1, 2, and 5 to be a population. Assume that samples of size 2 are randomly selected (with replacement) from the population. List the 9 different possible samples, and find the mean of each sample.
