The television show Ghost Whistler has been successful for many years. That show recently had a share of 23, meaning that among the TV sets in use, 23% were tuned to Ghost Whistler. Assume that an advertiser wants to verify that 23% 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 Ghost Whistler broadcast. Find the probability that none of the households are tuned to Ghost Whistler. Find the probability that at least one household is tuned to Ghost Whistler. Find the probability that at most one household is tuned to Ghost Whistler. If at most one household is tuned to Ghost Whistler, does it appear that the 23% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Ghost Whistler unusual?) 0 yes, it is wrong 0 no, it is not wrong
