Consider the survey data in Exercise 1. 

a) What is the conditional distribution (in percents) of college presidents’ opinions about the value of college?
b) Find the conditional distribution of the opinions of U.S. adults when the categories are combined into Negative (poor), Middle (only fair), and Positive (good or excellent).

Data From Exercise 1

The Pew Research Center asked 2143 U.S. adults and 1055 college presidents to “rate the job the higher education system is doing in providing value for the money spent by students and their families” as Excellent, Good, Only Fair, or Poor.
