- Compute the residual for the observation (95.5, 94.0), the one marked with a triangle on Figure 7.6, using the linear model given in Equation 7.1.
- Take a look at the residual plot in part (a) of question 7.2 on page 296. Imagine the x-y scatterplot for these data. Based on the residual plot, what can you about the scatterplot?
- Assuming that the line of best fit for the possum data seen in Figure 7.4 is indeed y = 41 + 0.59x, what does the number 0.59 tell you about possums?
- What's one question you have about the reading?
