In a multiple regression analysis involving 24 data points, the mean squares for error, MSE, is 2, and the sum of squares for error, SSE, is 36. The number of the predictor variables must be:
A) 7
B) 6
C) 5
D) 4
E) 3

The number of predictor variables can be found using the formula: SSE = MSE * (n - k - 1), where n is the number of data points and k is the number of predictor variables. Here, 36 = 2 * (24 - k - 1). Solving for k gives k = 5.
