Suppose that a recent poll found that 41% of adults believe that the overall state of moral values is poor. Complete parts (a) through (c). (a) For 100 randomly selected adults, compute the mean and standard deviation of the random variable X, the number of adults who believe that the overall state of moral values is poor. The mean of X is 41. (Round to the nearest whole number as needed.) The standard deviation of X is 4.9. (Round to the nearest tenth as needed.) (b) Interpret the mean. Choose the correct answer below. A. For every 100 adults, the mean is the minimum number of them that would be expected to believe that the overall state of moral values is poor. B. For every 100 adults, the mean is the number of them that would be expected to believe that the overall state of moral values is poor. Your answer is correct.C. For every 100 adults, the mean is the range that would be expected to believe that the overall state of moral values is poor. D. For every 41 adults, the mean is the maximum number of them that would be expected to believe that the overall state of moral values is poor. (c) Would it be unusual if 41 of the 100 adults surveyed believe that the overall state of moral values is poor? Yes No

In a recent telephone survey, 5,000 randomly selected teenagers were asked to cite their primary social network site. Six of 10 teenagers said they use Mybook as their primary social network site. A 95% confidence interval to estimate the true proportion of teenagers who use Mybook as their primary social network site is found to be (0.2964, 0.9036). Which of the following is a correct interpretation of the confidence level?Ninety-five percent of all samples of this size would yield a confidence interval of (0.2964, 0.9036). There is a 95% chance that the true proportion of teenagers who use Mybook as their primary social network site is in the interval (0.2964, 0.9036). Ninety-five percent of the time, the procedure used to generate this interval will capture the true proportion of teenagers who use Mybook as their primary social network site. Ninety-five percent of all the samples of size 5,000 lie in the confidence interval (0.2964, 0.9036). There is a 95% chance that randomly selected teenagers will be part of the 60% who use Mybook as their primary social network site.
