Wine and cancer in women. Some studies have suggested that a nightly glass of wine may not only take the edge off a day but also improve health. Is wine good for your health? A study of nearly 1.3 million middle-aged British women examined wine consumption and the risk of breast cancer. The researchers were interested in how risk changed as wine consumption increased
| wine intake x(grams of alcohol per day) | 2.5 | 8.5 | 15.5 | 26.5 |
| Relative risk y | 1.00 | 1.08 | 1.15 | 1.22 |
Following is the scatter plot
The scatter plot shows upward sloping pattern,so we expect positive correlation
This scatter plot shows a very close to straight line pattern,so
we expect correlation coefficient to be close to 
1
