Barron's reported that the average number of weeks an 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. What is the probability that a simple random sample of 50 unemployed individuals will provide a sample mean within 1 week of...

One way of checking the effect of undercoverage, nonresponse, and other sources of error in a sample survey is to compare the sample with known facts about the population. About 14% of American adults are black. The numbers X of blacks in a random sample of 1700 adults should therefore vary with the binomial (n = 1700, p = 0.14) distribution. (a) What are the mean and standard deviation of X? (Round your standard deviation to three decimal places.) mean...
