A consumer advocate claims that 70 percent of cable television subscribers are not satisfied 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 4 cable subscribers is selected. Assuming independence, use an appropriate formula to compute the probability that 3 or more subscribers in the sample are not satisfied with...

A Gallup poll of 1,236 adults showed that 12% of the respondents believe that it is bad luck to walk under a ladder. Suppose 30 people are selected at random from among the 1,236 were polled, and further suppose we want to calculate the probability that at least 2 of the 30 believe it is bad luck to walk under a ladder. Given that the 30 subjects were selected without replacement, those selections are not independent. Can the probability be...

Employee Satisfaction Rates: A recent poll suggests that 48% of Americans are satisfied with their job. You have a company with 226 employees and a poll suggests that 89 of them are satisfied (about 39%). (a) Assume the 48% general satisfaction rate is accurate. In all random samples of 226 Americans, what is the mean and standard deviation for the number of people satisfied with their job? Round both answers to 1 decimal place. \muμ = \sigmaσ = (b) Convert...
