Question:
Assume that the population of heights of adult males has a normal distribution with a mean of m = 174.1 centimeters (cm) and a standard deviation of s = 7.1 cm.
a. If a sample of size n = 100 adult males results in a mean height of x = 172.0 cm, how many standard deviations is the sample mean away from the population mean?
b. What is the probability that the second sample of 100 adult males will have a mean of less than 172.0 cm?
