Bootstrap t confidence interval. Recall Example 16.2 (page 16-4). Suppose that a bootstrap distribution was created using 3000 resamples and that the mean and standard deviation of the resample means were 23.29 and 3.90, respectively. (a) What is the bootstrap estimate of the bias? (b) What is the bootstrap standard error of x? (c) Assume that the bootstrap distribution is reasonably Normal. Since the bias is small relative to the observed x, the bootstrap t confidence interval for the population mean m is justified. Give the 95% bootstrap t confidence interval for m.
