Question:
In Problem 14.3 on page 541, you predicted nonprofit charitable commitment, based on nonprofit revenue (Revenue) and fundraising efficiency (Efficiency) for a sample of 98 nonprofit organizations. Use the following results:
a. Construct 95% confidence interval estimates of the population slope between commitment and revenue and between commitment and efficiency.
b. At the 0.05 level of significance, determine whether each independent variable makes a significant contribution to the regression model. On the basis of these results, indicate the independent variables to include in this model.
