In a regression model involving 30 observations, the following estimated regression equation was obtained:
Y(hat) = 17 + 4X1 - 3X2 + 8X3 + 8X4
For this model SSR = 700 and SSE = 100.
The coefficient of determination for the above model is approximately
The conclusion is that the
A. model is not significant
B. model is significant
C. slope of X1 is significant
D. slope of X2 is significant
The solution provides step by step method for the calculation of coefficient of determination. Formula for the calculation and Interpretations of the results are also included.
