Some studies have suggested that a nightly glass of wine may not only take the edge off of the day but also improve 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. Risk is based on breast cancer rates in drinkers relative to breast cancer rates in nondrinkers in the study, with higher values indicating higher risk. In particular, a value greater than 1 indicates a greater breast cancer rate than that of nondrinkers. Wine intake is the mean wine intake, in grams of alcohol per day (1 glass of wine is approximately 10 grams of alcohol), of all women in the study who drank approximately the same amount of wine per week. 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 a. Make a scatterplot of these data using technology, and draw a quick sketch of it below.
