Here is a sample of amounts of weight change (kg) of college students in their freshman year: 10, 7,6, -7, where -7 represents a loss of 7 kg and positive values represent weight gained. Here are ten bootstrap samples: (10, 10, 10, 6}, {10, -7, 6, 10}, {10, -7, 7, 6), {7.-7, 6, 10}, {6, 6, 6, 7}, {7, - 7, 7, - 7), {10, 7, -7, 6}, {- 7, 7, - 7, 7}, {- 7, 6, – 7, 7}, {7, 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

Question
Here is a sample of amounts of weight change (kg) of college students in their freshman year: 10, 7,6, -7, where -7 represents a loss of
7 kg and positive values represent weight gained. Here are ten bootstrap samples: (10, 10, 10, 6}, {10, -7, 6, 10}, {10, -7, 7, 6),
{7.-7, 6, 10}, {6, 6, 6, 7}, {7, - 7, 7, - 7), {10, 7, -7, 6}, {- 7, 7, - 7, 7}, {- 7, 6, – 7, 7}, {7, 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.
