In a recent poll, the Gallup Organization found that 45% of adult Americans believe that the overall state of moral values in the United States 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 overal state of moral values, complete parts (a) through (g) below (4) Explain why this is a binomial experiment. Select all that apply A Each trial depends on the previous trial B. The trials are independent DC There are mutually exclusive outcomes, success or failure D. The probability of success is different for each trial of the experiment DE The probability of success is the same for each trial of the experiment The meperiment in performed a fixed number of times G. There are too mutusty exclusive pousble outcomes, arriving on-time, arivengeany, and ange Thement is performed sant a desped number of successes are reached

(b) Using the binomial distribution, determine the values of n and p n= (Type an integer or a decimal. Do not round.) ph (Type an integer or a decimal. Do not round.) (c) Using the binomial distribution, 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 fool the state of morals is poor is (Round to four decimal places as needed) Interpret the results In 100 bals of this experiment, wo expect about to result in exactly 9 adults who feel the state of morals is poor (Round to the nearest whole number as needed)

(d) Using the binomial distribution, find and interpret the probability that no more than 4 of those surveyed feel the state of morals is poor 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 In 100 trials of this experiment, we expect about to result in no more than 4 adults who fool the state of morals is poor (Round to the nearest whole number as needed.) (e) Using the binomial distribution, 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 In 100 trials of this experiment, we expect about (Round to the nearest whole number as needed.) (f) Using the binomial distribution, find and interpret the probability that 7 or 8 believe the state of morals is poor to result in more than 11 adults who feel 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. In 100 trials of this experiment, we expect about to result in 7 or 8 adults who feel the state of morals is poor (Round to the nearest whole number as needed)

(g) Using the binomial distribution, would it be unusual to find 12 or more adults in the sample who believe the overall state of moral values is poor? Why? OA. No, because the probability of 12 or more adults believing the overall state of moral values is poor is very high OB. Yes, because the probability of 12 or more adults believing the overall state of moral values is poor is very high OC. No, because the probability of 12 or more adults believing the overall state of moral values is poor is very low OD. Yes, because the probability of 12 or more adults believing the overall state of moral values is poor is very low 27
