If we use the listed pulse rates with suitable methods of statistics, we conclude that when the 64.0 average (mean) of the pulse rates of the five males is compared to the 69.6 average (mean) of the pulse rates of the five females, there is a 36% chance that the difference can be explained by random results obtained from populations of males and females having the same average (mean) pulse rate. Does this prove that the populations of males and females have the same average (mean) pulse rate? Why or why not? Would better results be obtained with larger samples?

Pulse Rate (beats per minute) Male Female 60 64 60 72 64 68 72 60 60
