Lesson 3 - Student Task # 31. Complete the statement by filling in the blank. Write your answer on a separate sheet of paper.Ais a frequency distribution using the means computed from all possible randomsamples of a specific size taken from a population. To get the possible samples use the formulawhere N is theand n is thesize to be taken. The total probability of thesample mean must be equal to2. Construct a sampling distribution of sample mean and its probability. Samples of 3 cards aredrawn from a population of five cards numbered from 1-5.

A political newspaper, Politically Sound, is interested in the distances voters in Rising Falls County live from their nearest polling station. Politically Sound has hired you to estimate the population mean of all such distances for voters in this county. To estimate this population mean, you select a random sample of 17 Rising Falls County voters and record the distance (in km) each voter lives from their nearest polling station. Assume the population is approximately normally distributed. Based on your sample, follow the steps below to construct a 99% confidence interval for the population mean of all the distances voters in Rising Falls County live from their nearest polling station. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results for your random sample.
