PLEASE HELPPPPP!!!!!! THE FIRST ONE IS WRONG AND IDK WHYYYY A leading magazine (like Barron's) reported...
Right Answer needed please. A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 39 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 39 weeks and that the population standard deviation is 2.8 weeks. Suppose you would like to select a random sample of 85 unemployed individuals for a follow-up study Find the probability that a single randomly selected value is...
Please help me with this A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 38 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 38 weeks and that the population standard deviation is 6 weeks. Suppose you would like to select a random sample of 35 unemployed individuals for a follow-up study Find the probability that a single randomly selected value...
A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 39 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 39 weeks and that the population standard deviation is 2.4 weeks. Suppose you would like to select a random sample of 77 unemployed individuals for a follow-up study. Find the probability that a single randomly selected value is greater than 38.9. P(X...
