Question

Consider the approximately normal population of heights of male college students with
mean u = 67 inches and standard deviation of o = 3.2 inches. A random sample
of 11 heights is obtained.
(e) Find P(x > 65). (Round your answer to four decimal places.)
0.734
(f) Find P(x < 63). (Round your answer to four decimal places.)
.5

Expert Solution

Step 1

The Z-score of a random variable X is defined as follows:

Z = (X – µ)/σ.

Here, µ and σ are the mean and standard deviation of X, respectively.
