icang [17]

Answer: D. .400

Step-by-step explanation:

Given : In a multiple regression model involving 44 observations, the following estimated regression equation was obtained.

\hat{Y}= 29 + 18x_1 + 43x_2 + 87x_3

For this model,

Regression sum of squares =SSR = 600

and Sum of squares due to error =SSE = 400.

Total sum of squares = SST= SSR+SSE

SST= 600+400=1000

The multiple coefficient of determination is given by :-

R^2=1-\dfrac{SSR}{SST}

Substitute values , we get

R^2=1-\dfrac{600}{1000}

R^2=1-0.600=0.400

Thus, the multiple coefficient of determination for the above model is R^2=0.400

Hence, the correct answer is D. .400.
