Question

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

= 30 + 18x₁ + 43x₂ + 87x₃
For this model, SSR = 800 and SST = 1400. The multiple correlation coefficient for the above model is

Quizplus · Accepted Answer

The coefficient of determination (R-squared) is calculated as SSR/SST, which is 800/1400 = 0.57. Taking the square root of R-squared gives us the multiple correlation coefficient, which is √0.57 = 0.75. Therefore, the correct answer is B.
