ges of Proofreaders
At a large publishing company, the mean age of proofreaders is 36.2 years and the standard deviation is 3.7 years. Assume the variable is normally distributed. Round intermediate z -value calculations to two decimal places and the final answers to at least four decimal places.

If a proofreader from the company is randomly selected, find the probability that his or her age will be between 35  and 36.5 years.

If a random sample of

 proofreaders is selected, find the probability that the mean age of the proofreaders in the sample will be between 35 and 36.5  years. Assume that the sample is taken from a large population and the correction factor can be ignored.
