(3 points) Consider a population of 5 literature students. Each student was assigned a final paper assignment. For each student (S, for student 1, S2 for student 2, etc.), the number of pages the student wrote for his or her paper is listed below: S1 = 81, $2 = 19, $3 = 43, 54 = 15, $5 = 38 This Is a multi-step problem. Part 1: Find the mean of the population. Round to 4 decimal places if necessary. Answer. | 39.2 Part 2: Find the standard deviation of the population. Round to 4 decimal places if necessary. Answer. 23.481 Part 3: All the possible samples of size n = 2 are listed in the first column of the table below. 1) For all the possible samples, calculate the sample mean and put that value in the second column. Do not round any quantities. il) For all the possible samples, calculate the sampling error, and put that value in the third column. Samples of Size n=2 Sample Means Sampling Errors 81, 19 81, 43 81, 15 81, 38 19, 43 19, 15 19. 38 43, 15 43, 38 15, 38
