Question

Suppose that we are interested in exploring the determinants of successful high schools. One possible measure of success might be the percentage of students who go on to college. The teachers' union argues that there should be a relationship between the average teachers' salary and high school success. The following regression line is obtained: "% of students going on to college = 13 + 0.001(Average Teachers' Salary)." Which of the following statements is true with respect to the given scenario? Select one: a. If the percentage of students going on to college increases by 0.001, we would expect the average teachers' salary to approximately increase by one dollar. b. If the average teachers' salary increases by one dollar, we would expect the percentage of students going on to college to increase approximately by 0.001 percent. c. If the percentage of students going on to college increases by 1, we would expect the average teachers' salary to approximately increase by 0.001 dollar. d. If the average teachers' salary increases by 0.001 dollar, we would expect the percentage of students going on to college to increase approximately by one percent.
