Barron's reported that the average number of weeks an individual is unemployed is 16 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 16 weeks and that the population standard deviation is 6 weeks. Suppose you would like to select a random sample of 55 unemployed individuals for a follow-up study. Use z-table. a. Show the sampling distribution of , the sample mean average for a sample of 55 unemployed individuals. E(7) = 16 (to 1 decimal) oz = 0.8090 (to 4 decimals) Choose the correct graph.
