Question

In 1995 the proportion of people who bought cable was 93%. Since the introduction of streaming services, you have reason to believe that that percentage has changed. A sample of 1000 people in 2017 saw that the percentage of those people who bought cable was down to 63%. Perform the hypothesis test at the 5% significance level.

1. Conduct the test using the rejection region approach or the p-value approach with a significance level of 0.02.

2. Give the 95% confidence interval for the proportion of people who bought cable in 2017, with its interpretation. (I know null hypothesis = .63 and alternative is not = .63)
