a) Null and alternative hypothesis b) Appropriate test to use c) Tail of the distribution d) Decision Rule 2. A study was conducted to investigate the effects of exercise on stress. The table below lists systolic blood pressure readings (in mmHg) of subjects from the time preceding 25 minutes of aerobic bicycle exercise and preceding the introduction of stress through arithmetic and speech tests (based on data from "Sympathoadrenergic Mechanisms in Reduced Hemodynamic Stress Response after Exercise"). Use a 1% level of significance to test the claim that the different groups of subjects have the same mean blood pressure.

2. A study was conducted to investigate the effects of exercise on stress. The table below lists systolic blood pressure readings
(in mmHg) of subjects from the time preceding 25 minutes of aerobic bicycle exercise and preceding the introduction of
stress through arithmetic and speech tests (based on data from "Sympathoadrenergic Mechanisms in Reduced
Hemodynamic Stress Response after Exercise"). Use a 1% level of significance to test the claim that the different groups of
subjects have the same mean blood pressure.
