Pulse Rates The author, at the peak of an exercise program, claimed that his pulse rate was lower than the mean pulse rate of statistics students. The author's pulse rate was measured to be 60 beats per minute, and the 20 students in his class measured their pulse rates. When testing the claim that statistics students have a mean pulse rate greater than 60 beats per minute, the accompanying TI-83 Plus calculator display was obtained. Based on those results, is there sufficient evidence to support the claim that the mean pulse rate of statistics students is greater than 60 beats per minute?
