Here are ten bootstrap samples: (10, 10, 10, 4). (10. - 2, 4, 10), (10, - 2, 5, 4), (5, - 2, 4, 10}, (4, 4, 4, 5), (5, - 2, 5, -2), (10, 5, - 2, 4), { -2, 5, -2, 5), { - 2, 4, - 2, 5}, (5, 10, 10, 10). 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
