Question 15 0/1 pt 9 10 99 0 Details Assume that a procedure yields a binomial distribution with a trial repeated n = 5 times. Find the probability of x = 4 successes given the probability p = 13/30 of success on a single trial. (Report answer accurate to 4 decimal places.) P(4) = Submit Question Question 16 0/1 pt 9 10 99 0 Details The television show Pretty Betty has been successful for many years. That show recently had a share of 28, meaning that among the TV sets in use, 28% were tuned to Pretty Betty. Assume that an advertiser wants to verify that 28% share value by conducting its own survey, and a pilot survey begins with 10 households have TV sets in use at the time of a Pretty Betty broadcast. Find the probability that none of the households are tuned to Pretty Betty. P(none) = Find the probability that at least one household is tuned to Pretty Betty. P(at least one) = Find the probability that at most one household is tuned to Pretty Betty. P(at most one) = If at most one household is tuned to Pretty Betty, does it appear that the 28% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Pretty Betty unusual?) No, it is probably not wrong because the probability that at most one household tuning in is not unusual. Yes, it is probably wrong because the probability that at most one household tuning in is unusual. Question Help: B Read Submit
