Ages 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. Use a TI-83 Plus/TI-84 Plus calculator and
round 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
36.3 and 37.6 years.
