b) Find the conditional distributions (percentages) of plans for the minority students.

c) Create a graph comparing the plans of white and minority students.

d) Do you see any important differences in the postgraduation plans of white and minority students? Write a brief summary of what these data show, including comparisons of conditional distributions.
