In a recent Pew Research poll, 54% out of a random sample of 3487 American adults 12. approve of the House of Representatives' decision to conduct an impeachment inquiry. i. Calculate a 99% confidence interval for the true proportion of American adults who approve of the inquiry. Make sure to check the assumptions for the interval. il. Which of the following is a correct interpretation of your interval? (Circle the letter of the best answer) a. There is a 99% chance the true proportion of American adults who approve of the inquiry is in my interval. b. If I took repeated samples of the same size and calculated confidence intervals each time, about 99% of the intervals would contain the sample proportion of American adults who approve of the inquiry. c. Tam 99% confident the true proportion of American adults who approve of the inquiry is in my interval d. The probability of capturing the true proportion of American adults who approve of the inquiry in my interval is .95 i. Does this interval provide significant evidence that a majority of American adults approve of the inquiry? Explain.
