A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 18.5 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 18.5 weeks and that the population standard deviation is 9 weeks. Suppose you would like to select a random sample of 50 unemployed individuals for a follow-up study. Find the probability that a single randomly selected value is between 14.8 and 16.2. P(14.8 < X < 16.2) = Find the probability that a sample of size N =50 is randomly selected with a mean between 14.8 and 16.2. P(14.8 < M < 16.2) = Enter your answers as numbers accurate to 4 decimal places.
