question 38

Here is a sample of amounts of weight change(kg) of college students in their freshmanyear: 10, 5, 0, 5, where 5 represents a loss of 5 kg and positive values represent weight gained. Here are ten bootstrapsamples: {10,10,10,0}, {10,5,0,10}, {10,5,5,0}, {5,5,0,10}, {0,0,0,5}, {5,5,5,5}, {10,5,5,0}, {5,5,5,5}, {5,0,5,5}, {5,10,10,10}. Complete parts(a) and(b) below.

a. Using only the ten given bootstrapsamples, construct an 80% confidence interval estimate of the mean weight change for the population.

----- kg<< ----kg

(Round to one decimal place asneeded.)

b. Using only the ten given bootstrapsamples, construct an 80% confidence interval estimate of the standard deviation of the weight changes for the population.
