A leading magazine (like Barron's) reported at one time that
the average number of weeks an individual is unemployed is
17 weeks. Assume that for the population of all
unemployed individuals the population mean length of
unemployment is 17 weeks and that the population
standard deviation is 3 weeks. Suppose you would like to
select a random sample of 36 unemployed individuals for a
follow-up study.
Find the probability that a single randomly selected value is
less than 16.
P(X < 16) =| 0.3694
