leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 32 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 32 weeks and that the population standard deviation is 4 weeks. Suppose you would like to select a random sample of 55 unemployed individuals for a follow-up study. Find the probability that a single randomly selected value is greater than 31.7. P(X > 31.7) = (Enter your answers as numbers accurate to 4 decimal places.) Find the probability that a sample of size n=55n=55 is randomly selected with a mean greater than 31.7. P(M > 31.7) = (Enter your answers as numbers accurate to 4 decimal place

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
