individual is unemployed is 17.5 weeks. Assume that for the
population of all unemployed individuals the population mean length
of unemployment is 17.5 weeks and that the population standard
deviation is 5 weeks. Suppose you would like to select a sample of
50 unemployed individuals for a follow-up study.
