(b) As a pedagogical exercise, find the correlation, r, step by step. You may wish to round off to two decimal places in each step. First, obtain the mean and standard deviation of each variable. Second, compute the four standardized values
for each variable. Finally, use the formula for r. Use your calculator or software to obtain and check that you get the
same result as in your hand calculations, up to roundoff error (linter your answer rounded to two decimal places),

14 ft 7 inches
