More on service center call lengths. Here is an SRS of 10 of the service center call lengths from Exercise 16.14: CALLS10 104 102 35 211 56 325 67 9 179 59 We expect the sampling distribution of x to be less close to Normal for samples of size 10 than for samples of size 80 from a skewed distribution. (a) Create and inspect the bootstrap distribution of the sample mean for these data using 1000 resamples. Compared with your distribution from the previous exercise, is this distribution closer to or farther away from Normal? (b) Compare the bootstrap standard errors for your two sets of resamples. Why is the standard error larger for the smaller SRS?
