Question: A survey in Newsweek (14 November 1994, p. 54) asked: "Does the Senate generally pay too much attention to personal lives of people nominated to high office, or not enough?" Fifty-six percent of the respondents said "too much attention." It was also reported that "for this Newsweek poll, Princeton Survey Research Associates telephoned 756 adults Nov. 3-4. The margin of error is 4 percentage points."

a. Verify that the margin of error reported by Newsweek is consistent with the rule given in this chapter for finding the approximate margin of error.

b. Based on these sample results, are you convinced that a majority of the population (that is, over 50%) think that the Senate pays too much attention? Explain.
