Problem 14E

A scatterplot contains four points: (-2,-2), (-1,-1), (0,0), and (1,1). A fifth point, (2,y), is to be added to the plot. Let r represent the correlation between x and y.

a. Find the value of y so that r = 1.

b. Find the value of y so that r = 0.

c. Find the value of y so that r = 0.5.

d. Find the value of y so that r = −0.5.

e. Give a geometric argument to show that there is no value ofy for which r =−1.
