Question:

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.
