Question: Public opinion. For many years Martha Stewart was a popular expert in home decorating, an arbiter of good taste, and a very successful businesswoman. In June 2002 she first came under attack amidst rumors of insider stock trading. At that time, a series of Gallup polls each contacted over 1000 people to ask about their overall opinion of her. Those polled could answer favorable, unfavorable, or that they did not know who she was. Results are summarized in the table on the following page.
a) Each poll should total 100%. Can you think of a reason why these do not?
b) How could the number of people who do not know who Martha Stewart is increase from June to July? Did people forget her? Or is the poll perhaps flawed? Explain how these results could be valid.
c) Display these results in a bar graph.
d) Display these results with pie charts.
e) Display these results with a timeplot.
f) Which display do you think best depicts these data? Why?
g) Write a few sentences describing Martha Stewart's public image at that time.
