Q5: The Fox TV network is considering replacing one of its prime-time crime investigation shows with a new family-oriented comedy show. Before a final decision is made, network executives commission a sample of 400 viewers. After viewing the comedy, 250 indicated they would watch the new show and suggested it replace the crime investigation show. Develop a 99 percent confidence interval for the population proportion.

When asked whether marriage is becoming obsolete, 784 out of 1978 randomly selected adults who responded to a poll said yes. Assuming the conditions for the CLT were met. a) Use your calculator to report a 95% confidence interval for the single proportion. Report both the minimum and maximum number in the interval. As part of your answer, write what you typed into your calculator to create the confidence interval. b) Use your confidence interval to answer whether it is plausible to claim that a majority think marriage is becoming obsolete? Why or why not?
