(a) A survey of 786 adults showed that 68% thought TV contributed to a decline in family values. If the sample was randomly selected, what can you say about the proportion of all adults who think TV contributes to a decline in family values? (Discuss whether the conditions for using a confidence interval are met, give the confidence interval itself,...
