One measure of physical fitness is the amount of time it takes for the pulse rate to return to normal after exercise, which is called the pulse-recovery time. A random sample of 20 women aged 40-50 exercised on stationary bicycles for 30 minutes. The amount of time it took for their pulse rates to return to pre- exercise levels was measured and recorded. The sample mean was 16.5 minutes and the sample standard deviation was 3.55 minutes. 24. Find the 95% confidence interval for the mean pulse-recovery time for all women aged 40-50.
