a. Construct a scatterplot and compute r for the association of the variables x and y described in Table 35.

b. Add 10 to each of the x values in Table 35. Then construct a scatterplot and compute r. How do the scatterplot and r com- pare to your results in part (a)? Why does this make sense?
c. Add 3 to each of the y values in Table 35. Then construct a scatterplot and compute r. How do the scatterplot and r com- pare to your results in part (a)? Why does this make sense?
