Pulse Rates: Pulse rate is an important measure of fitness of a person's cardiovascular system. The mean pulse rate for all U.S. adult males is approximately 72 heart beats per minute. A random sample of 21 U.S. adult males who jog at least 15 miles per week had a mean pulse rate of 53.6 beats per minutes and a standard deviation of 3.23 beats per minutes. a) Find the 95% confidence interval for the mean pulse rate of all U.S. adult males who jog at least 15 miles per week. Round to 1 decimal place. Write the answer using the format: lower boundary < u < upper boundary b) Does it appear that jogging at least 15 miles per week reduces the mean pulse rate for adult males? Explain your answer.
