Question: Refer to problem (9). Using the formula on page 444 in our textbook, construct the 95% confidence interval for the difference in proportions p₁ - p₂, where p₁ is the proportion of 36 – 50 year olds who get their news primarily from newspapers, and p₂ is the proportion of over 50 year olds who get their news primarily from newspapers. Interpret the results. Compare this confidence interval to your hypothesis test result in #9. Explain why you would reject the null hypothesis if the confidence interval did not contain zero.
