Question: 16.43 Bootstrap confidence intervals for the difference in average repair times. Example 16.6 (page 16-17) considers the mean difference between repair times for Verizon (ILEC)

16.43 Bootstrap confidence intervals for the difference in average repair times. Example 16.6 (page 16-17) considers the mean difference between repair times for Verizon (ILEC) customers and customers of competing carriers (CLECs). The bootstrap distribution is non-Normal with strong left-skewness, so that any t confidence interval is inappropriate. Give the BCa 95% confidence interval for the mean difference in service times for all customers. In practical terms, what kind of error would you make by using a t interval or percentile interval instead of a BCa interval?
