In a multiple regression analysis involving 15 independent variables and 200 observations, SST = 800 and SSE = 240. The adjusted coefficient of determination is
A) 0.15
B) 0.50
C) 0.66
D) 0.70

The adjusted R-squared is calculated using the formula: 1 - [(SSE/(n-k-1)) / (SST/(n-1))], where n is the number of observations and k is the number of independent variables. Plugging in the values: 1 - [(240/(200-15-1)) / (800/(200-1))] = 0.66.
