Question

A realtor studied the relation between x = yearly income (in thousands of dollars per year) of home purchasers and y = sale price of the house (in thousands of dollars). The realtor gathered data from mortgage applications for 24 sales in the realtor’s basic sales area in one season.
a. A scatterplot with a LOWESS smoother, drawn using Minitab, follows. Does the relation appear to be basically linear?
b. Are there any high leverage points? If so, which ones seem to have high influence?
