Problem 109MEE
Suppose that we have n pairs of observations (xi , yi ) such that the sample correlation coefficient r is unity (approximately). Now let zi = y2i and consider the sample correlation coefficient for the n-pairs of data (xi , zi ). Will this sample correlation coefficient be approximately unity? Explain why or why not.
