Assume that pulse rates of men follow a bell-shaped (normal) distribution with a mean of 74 beats per minute and a standard deviation of 12 beats per minute.
a.	Based upon the Range Rule of Thumb, give an interval that contains 95% of all such pulse rate values.
b.	What would be the z-score (standard score) of an individual with a pulse rate of 82 beats per minute?
c.	If the z-score (basic standardized score) of an individual was stated to be 1.25, what would be his pulse rate?
