According to a study, 66% of all males between the ages of 18 and 24 live at home. (Unmarried college students living in a dorm are counted as living at home.) Suppose that a survey is administered and 140 of 207 respondents indicated that they live at home. (a) Use the normal approximation to the binomial to approximate the probability that at least 140 respondents live at home. (b) Do the results from part (a) contradict the study?
According to a study, 47% of all males between the ages of 18 and 24 live at home. (Unmarried college students living in a dorm are counted as living at home.) Suppose that a survey is administered and 125 of 234 respondents indicated that they live at home. (a) Use the normal approximation to the binomial to approximate the probability that at least 125 respondents live at home. (b) Do the results from part (a) contradict the study?

According to a study, 77% of adults ages 18-29 years had broadband Internet access at home in 2011. A researcher wanted to estimate the proportion of undergraduate college students (18-23 years) with access, so she randomly sampled 186 undergraduates and found that 166 had access. Estimate the true proportion with 99% confidence. Round your answers to three decimal places. Source: World Almanac 2012. Sp
