A set of bivariate data consists of these measurements on two variables, x and y:

a. Draw a scatterplot to describe the data.
b. Does there appear to be a relationship between x and y? If so, how do you describe it?
c. Calculate the correlation coefficient, r, using the computing formula given in this section.
d. Find the best-fitting line using the computing formulas. Graph the line on the scatterplot from part a. Does the line pass through the middle of the points?
