A marketing research firm wishes to study the relationship
between wine consumption and whether a person likes to watch
professional tennis on television. One hundred randomly selected
people are asked whether they drink wine and whether they watch
tennis. The following results are obtained:
| Watch Tennis |
Do Not Watch Tennis |
Totals | |
| Drink Wine | 10 | 36 | 46 |
| Do Not Drink Wine | 10 | 44 | 54 |
| Totals | 20 | 80 | 100 |
(a) For each row and column total, calculate the corresponding row or column percentage.
| Row 1 | % |
| Row 2 | % |
| Column 1 | % |
| Column 2 | % |
(b) For each cell, calculate the corresponding
cell, row, and column percentages. (Round your answers to
the nearest whole number.)

Consider the relationship between yearly wine consumption
(liters of alcohol from drinking wine, per person) and yearly
deaths from heart disease (deaths per 100,000 people) in 19
developed countries. Suppose that you read a newspaper article in
which the reporter states the following: Researchers find the
correlation between yearly wine consumption and yearly deaths from
heart disease is -0.84. Thus, it is reasonable to conclude that
increased consumption of alcohol from wine causes fewer deaths from
heart disease in industrialized...
