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 24% of the canadian population over 15 years of age are first generation; that is, they were born outside canada. the number x of first-generation canadians in random samples of 1000 persons over 15 should therefore vary with the binomial (n = 1000, p = 0.24) distribution.
(a) what are the mean and standard deviation of x?
(b) use the normal approximation to find the probability that the sample will contain between 210 and 270 first-generation canadians. be sure to check that you can safely use the approximation.
