Extracted text: 7.70 CABLE TV SUBSCRIPTIONS VS. STREAMING SERVICES. Refer to the 2018 CNBC All American Survey discussed in Exercise 6.460. Recall that a poll was conducted on a representative sample of 800 US adults in order to investigate the decline in cable and satellite TV subscriptions. For this sample, 160 adults revealed that they are "cord cutters," (i.e., they canceled their cable/satellite TV service and now only use a video streaming service like Netflix or Hulu). Recall that a cable TV executive claims that p, the true proportion of all US adults who are "cord cutters," is only .10. You desire to test this claim using a = .05. a. Write Ho and Ha for this test in symbols and in the problem's context. b. Calculate the test statistic. c. Give the rejection region for the test. d. Calculate the p-value for the test. e. Write the conclusion in the problem's context.
