Suppose that a recent poll found that 50% of adults in a certain country believe that the overall state of moral values is poor. If a survey of a random sample of 15 adults in this country is conducted in which they are asked to disclose their feelings on the overall state of moral values, complete parts (a) through (e) below. Click here to view the table for the binomial probability distribution. Click here to view the table for the cumulative binomial probability distribution. (a) Find and interpret the probability that exactly 9 of those surveyed feel the state of morals is poor. The probability that exactly 9 of those surveyed feel the state of morals is poor is. (Round to four decimal places as needed.) Interpret the results. Choose the correct answer below. In 100 trials of this experiment, we expect about to result in exactly 9 adults who feel the state of morals is poor. (b) Find and interpret the probability that no more than 4 of those surveyed feel the state of morals is por. The probability that no more than 4 of those surveyed feel the state of morals is poor is. (Round to four decimal places as needed.) Interpret the results. Choose the correct answer below. In 100 trials of this experiment, we expect about to result in no more than 4 adults who feel the state of morals is poor. (c) Find and interpret the probability that more than 11 of those surveyed feel the state of morals is poor. The probability that more than 11 of those surveyed feel the state of morals is poor is (Round to four decimal places as needed.) Interpret the results. Choose the correct answer below. In 100 trials of this experiment, we expect about to result in more than 11 adults who feel the state of morals is poor.

(d) Find and interpret the probability that 7 or 8 believe the state of morals is poor. The probability that 7 or 8 believe the state of morals is poor is (Round to four decimal places as needed.) Interpret the results. Choose the correct answer below. In 100 trials of this experiment, we expect about to result in 7 or 8 adults who feel the state of morals is poor. (e) Would it be unusual to find 12 or more adults in the sample who believe the overall state of moral values is poor? Why? O A. No, because the probability of 12 or more adults believing the overall state of moral values is poor is very low. B. No, because the probability of 12 or more adults believing the overall state of moral values is poor is very high. C. Yes, because the probability of 12 or more adults believing the overall state of moral values is poor is very high. D. Yes, because the probability of 12 or more adults believing the overall state of moral values is poor is very low.
