question 9

Here is a sample of amounts of weight change(kg) of college students in their freshmanyear: 11, 9, 1, 6, where 6 represents a loss of 6 kg and positive values represent weight gained. Using the 200 given bootstrapsamples, complete parts(a) and(b) below

a. Construct a 95% confidence interval of the mean weight change for thepopulation, using the 200 bootstrap samples.

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

(Round to one decimal place asneeded.)

b. Construct a 95% confidence interval estimate of the standard deviation of the weight changes for thepopulation, using the 200 bootstrap samples.

------ kg

(Round to one decimal place asneeded.)
