A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 31 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 31 weeks and that the population standard deviation is 4.9 weeks. Suppose you would like to select a random sample of 167 unemployed individuals for a follow-up study. Find the probability that a single randomly selected value is between 30.5 and 31.6. P(30.5 < X < 31.6) = Correct Find the probability that a sample of size n=167n=167 is randomly selected with a mean between 30.5 and 31.6. P(30.5 < M < 31.6) = Enter your answers as numbers accurate to 4 decimal places.
