The number of math degrees granted by Northwestern University are shown in Table 30 for various years.

Let n be the number of math degrees granted by Northwestern University in the year that is t years since 2000.
a. Construct a scatterplot.
b. Is there a linear association, a nonlinear association, or no association?
c. Compute r. On the basis of the scatterplot and r, determine the strength of the association.
d. Is the association positive, negative, or neither? What does that mean in this situation?
e. What is the drop in math majors from 2008 to 2009? Give at least one reason why this result stands out.
