Question 4
According to a study done by Pierce College JBLM, the height for
Hawaiian adult males is normally distributed with an average of 66
inches and a standard deviation of 2.5 inches. Suppose one Hawaiian
adult male is randomly chosen. Let X = height of the
individual.
Find the probability that the person is between 63.5 and 68.5
inches. Please explain how you derived this answer.
Question 5
The heights of the 430 Candidates for the Elite Military Unit

and a standard deviation, ? = 3.89 inches.
For the height of 77 inches, calculate the z-score and explain
