7.56 Influence: Monkey calls. Table 7.1 (page 191) contains data on the response of 37 monkey neurons to pure tones and to monkey calls. Figure 7.7 (page 192) is a scatterplot of these data. MONKEY

(a) Find the least-squares line for predicting a neuron's call response from its pure tone response. Add the line to your scatterplot. Mark on your plot the point (call it A) with the largest residual (either positive or negative) and also the point (call it B) that is an outlier in the x direction.

(b) How influential are each of these points for the correlation r?

(c) How influential are each of these points for the regression line?
