Answer #1

On the first statistics exam, the coefficient of determination between the hours studied and the grade earned was 78%. The standard error of estimate was 11. There were 25 students in the class. Develop an ANOVA table for the regression analysis of hours studied as a predictor of the grade earned on the first statistics exam. (Leave no cells blank - be certain to enter "0" wherever required. Round your answers to 2 decimal places.)

standard error = 11, MSE = 121

df for error = 23, SSE= MSE*df = 121*23=2783

coefficient of determination= 78% or 0.78

coefficient of nondetermination= 22% or 0.22

SSE/SST= 0.22

2783/SST =0.22, SST=12650
