Checking for survey errors. One way of checking the effect of undercoverage,nonresponse, and other sources of error in a sample survey is to compare thesample with known facts about the population. About 12% of American adultsare black. The number X of blacks in a random sample of 1500 adults shouldtherefore vary with the binomial (n = 1500, p = 0.12) distribution.(a) What are the mean and standard deviation of X?(b) Use the Normal approximation to find the probability that the sample willcontain between 165 and 195 blacks. Be sure to check that you can safely use theapproximation.
