a. Find r for the association of the variables x and y described in Table 36.

b. Subtract 5 from each of the x values in Table 36. Then construct a scatterplot and compute r. How do the scatterplot and r compare to your results in part (a)? Why does this make sense?
c. Subtract 2 from each of the y values in Table 36. Then construct a scatterplot and compute r. How do the scatterplot and r compare to your results in parts (a) and (b)? Why does this make sense?
