A consumer advocate claims that 80 percent of cable television subscribers are not satisfi ed with their cable service. In an attempt to justify this claim, a randomly selected sample of cable subscribers will be polled on this issue. (a) Suppose that the advocate's claim is true, and suppose that a random sample of five cable subscribers is selected. Assuming independence, use an appropriate formula to compute the probability that four or more subscribers in the sample are not satisfi ed with their service. (b) Suppose that the advocate's claim is true, and suppose that a random sample of 25 cable subscribers is selected. Assuming independence, fi nd (1) The probability that more than 20 subscribers in the sample are not satisfi ed with their service. (2) The probability that 15 or fewer subscribers in the sample are not satisfi ed with their service. (c) Suppose that when we survey 25 randomly selected cable television subscribers, we fi nd that 15 are actually not satisfi ed with their service. Using a probability you found in this exercise as the basis for your answer, do you believe the consumer advocate's claim? Explain
