Student survey revisited Chapter 2, Exercise 86 introduced a student survey in which 299 students were randomly selected and asked a variety of questions. One of the questions asked “How many friends do you have on Facebook?” To find a confidence interval for the mean number, a student drew 1000 bootstrap samples of the data and obtained the following histogram and summary statistics:

a) Use the data above to construct a 98% confidence interval for the mean number of Facebook friends a student has.

b) Interpret the interval you constructed in part a.

c) What assumptions did you make, if any, in interpreting the interval?
