Refer to Data Set 1 in Appendix B and use the pulse rates of males.
a. Find the mean and standard deviation, and verify that the pulse rates have a distribution that is roughly normal.
b. Treating the unrounded values of the mean and standard deviation as parameters and assuming that male pulse rates are normally distributed, find the pulse rate separating the lowest 2.5% and the pulse rate separating the highest 2.5%. These values could be helpful when physicians try to determine whether pulse rates are unusually low or unusually high.
