In Example 3.25 on page 207, we compare the mean hours of exercise per week between male and female college students. The sample results are included in the dataset Exercise Hours, where we see that the 20 men in the sample exercised for an average of 12.4 hours per week and the 30 women in the sample exercised for an average of 9.4 hours per week. Using the standard error for a bootstrap distribution, we find a 95% confidence interval for the difference in means (μ_m − μ_f) to go from −1.75 hours to 7.75 hours. Use StatKey or other technology and a bootstrap distribution to find and interpret a 90% confidence interval for the difference in mean hours of exercise between males and females. How does your interval compare to the 95% confidence interval based on the standard error?
