Homework: 7.4 HW - Bootstrapping: Using Technology for Estim Question 4, 7.4.7-T Part 1 of 2 HW Score: 50%, 3 of 6 points O Points: 0 of 1 Save Here is a sample of amounts of weight change (kg) of college students in their freshman year: 13, 8, 0, -2, where -2 represents a loss of 2 kg and positive values represent weight gained. Here are ten bootstrap samples: (13, 13, 13, 0), (13, -2, 0, 13), (13, -2, 8, 0), (8, -2, 0, 13), (0, 0, 0, 8), (8, -2, 8, -2), (13, 8, -2,0). (-2,8, -2,8). (-2, 0, -2, 8), (8, 13, 13, 13). Complete parts (a) and (b) below. a. Using only the ten given bootstrap samples, construct an 80% confidence interval estimate of the mean weight change for the population. kg<<kg (Round to one decimal place as needed.)
