Standard error versus the bootstrap standard error. We have two ways to estimate the standard deviation of a sample mean x: use the formula s 1n for the standard error, or use the bootstrap standard error. (a) Find the sample standard deviation s for the 60 IQ test scores in Exercise 16.8 and use it to find the standard error s 1n of the sample mean. How closely does your result agree with the bootstrap standard error from your resampling in Exercise 16.8? (b) Find the sample standard deviation s for the StubHub! ticket price data in Exercise 16.9 and use it to find the standard error s 1n of the sample mean. How closely does your result agree with the bootstrap standard error from your resampling in Exercise 16.9? (c) Find the sample standard deviation s for the eight video-watching times in Exercise 16.10 and use it to find the standard error s 1n of the sample mean. How closely does your result agree with the bootstrap standard error from your resampling in Exercise 16.10? 16
