It is claimed that due to smaller lung capacity, a female's heart must beat faster during exercise. Given this information, do females have a higher mean after exercise pulse rate [AEPLI than men? Perform this test at a 95% level of condence. It is believed that overweight people (high EFL-ill} will have a higher pulse difference because their heart must work comparatively harder when exercising. Given this information, can we predict a person's pulse difference {Y} using BM] {X}? In other words, is Eli-II a signicant predictor of a person's Pulse Difference? It is claimed that one minute of exercise will increase a typical STA332 student's pulse (mean pulse difference} by more than 25 heats per minute. At a 95% level of condence, evaluate this research objective (mean pulse difference is greater than 25 beats per minute)
