1. Suppose that a television news program conducts a call-in poll about a proposed city ban on
handgun ownership, with the result that 1921 of 2372 calls oppose the ban. Suppose further that
the news anchors make the following announcement: "81% of our sample opposed the ban, and
we can be 95% confident that the true proportion of citizens who oppose a handgun ban is
within 1.6% of the sample result."
a. Explain how the station calculated the 81% and 1.6% figures that it cites. (4 pts)
b. While their calculations are correct, the station has a major flaw in its process making the
conclusion invalid. Identify the flaw. (1 pts)
