A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 37.7 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 37.7 weeks and that the population standard deviation is 4.4 weeks. Suppose you would like to select a random sample of 12 unemployed individuals for a follow-up study. Find the probability that a single randomly selected value is between 34.3 and 34.5. P(34.3 < X < 34.5) =  Find the probability that a sample of size n=12n=12 is randomly selected with a mean between 34.3 and 34.5. P(34.3 < M < 34.5) =  Enter your answers as numbers accurate to 4 decimal places.
