The television show CSI: Shoboygan has been successful for many years. That show recently had a share of 20, meaning that among the TV sets in use, 20% were tuned to CSI: Shoboygan. Assume that an advertiser wants to verify that 20% share value by conducting its own survey, and a pilot survey begins with 13 households have TV sets in use at the time of a CSI: Shoboygan broadcast. (Round answers to four decimal places) Find the probability that none of the households are tuned to CSI: Shoboygan. P(none) = Find the probability that at least one household is tuned to CSI: Shoboygan. P(at least one) = Find the probability that at most one household is tuned to CSI: Shoboygan. P(at most one) = If at most one household is tuned to CSI: Shoboygan, does it appear that the 20% share value is wrong? (Hint: Is the occurrence of at most one household tuned to CSI: Shoboygan unusual?) O no, it is not wrong O yes, it is wrong
