American Moral Decline
In a survey conducted by Newsweek on June 2-3, 1994, 748 adults were asked, "Do you think the United States is in a moral and spiritual decline?" Of those who responded, 76% said "yes."
(a) Is this 76% a parameter or a statistic? Explain.
(b) Do you think that exactly 76% of all American adults would have answered "yes" to the question?
(c) Based on this sample survey result, do you think that the proportion of all American adults who would have answered "yes" to the question is closer to 76% or to 36%?
(d) Roughly how many percentage points would you have to go on either side of 76% to be about 95% confident that the interval would include the actual proportion of all American adults who would have answered "yes"?
