Data from 147 Colleges from 1995 to 2005 (Lee, 2008)

Data from 147 colleges from 1995 to 2005 (Lee, 2008) were used to predict the endowments (in billions) to a college from the average SAT score of students attending the college.The resulting regression equation was Ŷ = -20.46 + 4.06(X) .This regression indicates that:

A) most colleges have very high endowments.
B) for every one-point increase in SAT scores, a college can expect 4.06 billion more in endowments.
C) for every one-dollar increase in endowments, the college can expect a half-point increase in SAT scores.
D) for every one-point increase in SAT scores, a college can expect 20.46 billion fewer in endowments.
