The data below shows the selling price (in hundred thousands) and the list price (in hundred thousands) of homes sold. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the
P-value using a = 0.05. Is there sufficient evidence to conclude that there is a linear correlation between the two variables?
