A health psychologist knew that corporate executives in general have an
average score of 2.55 with a standard deviation of 0.5 on a stress
inventory and that the scores are normally distributed. In order to learn
whether corporate executives who exercise regularly have different stress
Scores, the psychologist measured the stress of 30 exercising executives
and found them to have a mean score of 2.76.
a. Using the five steps of hypothesis testing, was the group of 30
exercising executives different from executives in general? (Use the .05
significance level.) Be sure to sketch the distributions involved. Be sure to
fully state the five steps and show ALL calculations/work.
b. Additionally, explain the logic of what you did to a person who
understands hypothesis testing for studies in which the sample consists
of a single individual but is unfamiliar with hypothesis testing involving a
sample of more than one individual. (Be sure your explanation includes a
discussion of the distribution of means--what it is, what it is made of, the
concept of how it is created, how it's characteristics are created, its role in
the overall hypothesis testing process.)

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
