Question

Here is a sample of amounts of weight change (kg) of college students in their freshman year:15,7,4,−5,where −5 represents a loss of 5 kg and positive values represent weight gained. Here are ten bootstrap samples: (15,15,15,4),(15,-5,4,15),(15,-5,7,4),(7,-5,4,15),(4,4,4,7),(7,-5,7,-5),(15,7,-5,4),(-5,7,-5,7),(-5,4,-5,7),(7,15,15,15). Complete parts (a) and (b).

A. Using only the ten given bootstrap samples, construct an 80% confidence interval estimate of the mean weight change for the population. ___kg <μ<____kg.

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.
