Here are ten bootstrap samples: (11, 11, 11, 1}, {11, -2, 1, 11}, {11, -2, 5, 1}, {5, -2, 1, 11), (1, 1, 1, 5), (5, -2, 5, -2), (11, 5, -2, 1), (-2, 5, -2,5) {-2, 1, 2, 5), (5, 11, 11, 11). 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<μ< (Round to one decimal place as needed.) b. Using only the ten given bootstrap samples, construct an 80% confidence interval estimate of the standard deviation of the weight changes for the population. kasss ka
