Here is a sample of amounts of weight change (kg) of college students in their freshman year: 10, 8, 1, -8, where -8 represents a loss of 8 kg and positive values represent weight gained. Here are ten bootstrap samples: (10, 10, 10, 1), (10,-8, 1, 10), (10,-8, 8, 1), (8,-8, 1, 10), (1, 1, 1, 8), (8, 8, 8, -8), (10, 8, -8, 1), (-8, 8, 8, 8), (-8, 1,-8, 8), (8, 10, 10, 10). Complete parts (a) and (b) below. DO 05 a. Using only the ten given bootstrap samples, construct an 80% confidence interval estimate of the mean weight change for the population. kg<μ
