people in the age group 18-29 and 1500 people in the age group 30-55. The sample proportions of people whose main source of news is newspapers is 0.18 and 0.25 for the age groups 18-29 and 30-55, respectively. A. Find the 95% confidence interval for the difference in the proportion of people whose main source of news is newspapers for the two age groups and interpret it. B. At a= 0.10, can it be concluded that the proportion of those whose source of news is newspaper is higher in the age group 30-55? Use the p-value method.
