Here is a sample of amounts of weight change (kg) of college students in their freshman year 11, 2, -2, -6, where -6 represents a loss of 6 kg and positive values represent weight gained. Here are ten bootstrap samples (11. 11. 11-2), (11, -6, -2, 11), (11-6, 2, -2), (2, -6, -2, 11), (-2,-2, -2, 2), (2, -6, 2.-6). (11,2, 6-2), (-6, 2-6, 2), (-6, -2-6, 2), (2. 11. 11. 11) Complete parts (a) and (b) below A KILD a. Using only the ten given bootstrap samples, construct an 80% confidence interval estimate of the mean weight change for the population kg<μ (Round to one decimal place as needed)
