A nonprofit analyst seeks to determine which variables should be used to predict nonprofit charitable commitment, a nonprofit organization commitment to its charitable purpose. Two independent variables under consideration are Revenue, a measurement of total revenue, in billions of dollars, as a measure of nonprofit size

X1

and Efficiency, a measurement of the percent of private donations remaining after fundraising expenses as a measure of nonprofit fundraising efficiency

X2.

The dependent variable Y is Commitment, a measurement of the percent of total expenses that are allocated directly to charitable services. Both variables

X2

and Y are encoded as percents. Data are collected from a random sample of

97

nonprofit organizations, with the results provided in the accompanying table. Complete parts (a) through (c) below.
