62The Practice of Statistics for AP*, 4/e Chapter 3 Section 3.1 Check Your Understanding, page 144: 1. The explanatory variable is the number of cans of beer. The response variable is the blood alcohol level. 2. There are two explanatory variables: amount of debt and income. The response variable is stress caused by college debt. Check Your Understanding, page 149: 1. The relationship is positive. The longer the duration of the eruption, the longer the wait between eruptions is. One reason for this may be that if the geyser erupted for longer, it expended more energy and it will take longer to build up the energy needed to erupt again. 2. The form is roughly linear with two clusters. The clusters indicate that in general there are two types of eruptions, one shorter, the other somewhat longer. 3. The relationship is fairly strong. Two points define a line and in this case we could think of each cluster as a point, so the two clusters seem to define a line. 4. There are a few outliers around the clusters, but not many and not very distant from the main grouping of points. 5. The Starnes family needs to know how long the last eruption was in order to predict how long it will be until the next one. Check Your Understanding, page 154: 1. (a) The correlation is about 0.9. This indicates that there is a strong, positive linear relationship between the number of boats registered in Florida and the number of manatees killed. (b) The correlation is about 0.5. This indicates that there is a moderate, positive linear relationship between the number of named storms predicted and the actual number of named storms. (c) The correlation is about 0.3. This indicates that there is a weak, positive linear relationship between the healing rate of the two front limbs of the newts. (d) The correlation is about -0.1. This indicates that there is a weak, negative linear relationship between last year’s percent return and this year’s percent return in the stock market. 2. If we remove the outlier in this scatterplot, the correlation would decrease. This point has the effect of strengthening the observed linear relationship we see. Exercises, page 158: 3.1 Water temperature is the explanatory variable, and weight change (growth) is the response variable. Both are quantitative. 3.2 The explanatory variable is the type of treatment—removal of the breast or removal of only the tumor and nearby lymph nodes, followed by radiation, and survival time is the response variable. Type of treatment is a categorical variable, and survival time is a quantitative variable. 3.3 (a) A positive association between IQ and GPA means that students with higher IQs tend to have higher GPAs, and those with lower IQs generally have lower GPAs. The plot does show a positive association. (b) The form of the relationship is roughly linear, because a line through the scatterplot of points would provide a good summary. The positive association is moderately strong (with a few exceptions) because most of the points would be close to the line. (c) The lowest point on the plot is for a student with an IQ of about 103 and a GPA of about 0.4.
