Repeat Exercise 7 “Freshman 15” using a confidence level of 90% for parts 

(a) And 

(b) And using 1000 bootstrap samples instead of the 10 that were given in Exercise 7.

Data From Exercise 7

Here is a sample of amounts of weight change (kg) of college students in  their freshman year (from Data Set 6 “Freshman 15” in Appendix B): 11, 3, 0, -2, where  -2 represents a loss of 2 kg and positive values represent weight gained. Here are ten bootstrap samples: {11, 11, 11, 0}, {11, -2, 0, 11}, {11, -2, 3, 0}, {3, -2, 0, 11}, {0, 0, 0, 3}, {3, -2, 3, -2}, {11, 3, -2, 0}, { -2, 3, -2, 3}, { -2, 0, -2, 3}, {3, 11, 11, 11}.

In use technology to create the large number of bootstrap samples.
