The television show 50 minutes has been successful for many years. that show recently had a share of 29, meaning that among the tv sets in use, 29% were tuned to 50 minutes. assume that an advertiser wants to verify that 29% share value by conducting its own survey, and a pilot survey begins with 15 households have tv sets in use at the time of a 50 minutes broadcast. find the probability that none of the households are tuned to 50 minutes. p(none) = (round answer to 4 decimal places) find the probability that at least one household is tuned to 50 minutes. p(at least one) = (round answer to 4 decimal places) find the probability that at most one household is tuned to 50 minutes. p(at most one) = (round answer to 4 decimal places) if at most one household is tuned to 50 minutes, does it appear that the 19% share value is wrong? (hint: is the occurrence of at most one household tuned to 50 minutes unusual? ) a. yes, it is wrongb. no, it is not wrong
