A researcher decided to investigate gender differences in resting pulse rate (bpm). She collected data on 9 male and 9 female individuals. The resting pulse rates (bpm) of these individuals are listed as follows:

Males: 79, 90, 75, 60, 65, 79, 54, 98, 49

Females: 66, 59, 79, 95, 72, 55, 64, 60, 65

In answering the following, show your calculations.

1. Calculate the arithmetic mean pulse for each gender separately, and for both genders together
2. List the median pulse for each gender separately, and for both genders together.
3. What are the degrees of freedom associated with each gender separately and with both genders together?
4. Calculate the standard deviation in each gender separately.
5. Discuss what the measures calculated in "d" indicate for differences in gender.
6. Calculate the range and the interquartile range for both genders together.
