A multiple regression analysis includes 25 data points and 4 independent variables results in SST = 200 and SSR = 150.The multiple standard error of estimate will be:
A) 1.333.
B) 6.124.
C) 2.500.
D) 1.581.

The multiple standard error of estimate is calculated using the formula: sqrt(SSE / (n - k - 1)), where SSE = SST - SSR, n is the number of observations, and k is the number of independent variables. Here, SSE = 200 - 150 = 50, n = 25, and k = 4. Thus, the multiple standard error of estimate = sqrt(50 / (25 - 4 - 1)) = sqrt(50 / 20) = sqrt(2.5) = 1.581.
