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: 0/2 Part 1 of 2 If a proofreader from the company is randomly selected, find the probability that his or her age will be between 36.1 and 37.9 years. P (36.1 < X<37.9) - Part: 1/2 Part 2 of 2 X S 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 36.1 and 37.9 years. P(36.1
