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.
Part 1 of 2
If a proofreader from the company is randomly selected, find the probability that his or her age will be between 35.2 and 37.4 years.
P(35.2 <X< 37.4) =|
Part: 1/ 2
Part 2 of 2
If a random sample of 15 proofreaders is selected, find the probability that the mean age of the proofreaders in the sample will be between 35.2 and 37.4
years.
