Answer 1

$Step~6:~SST=Total~sum~of~square=6998.47\\ SSE=error~sum~of~square=3070\\ SSR=sum~of~squared~regression=SST-SSE\\ =6998.47-3070=3928.47\\ Proportion~of~variation=SSR/SST=3928.47/6998.47=0.56\\ Step~7.~Estimated~variance~of~the~error~term=MSE=SSE/10=307\\ Step~8:~Total~variability~of~dependent~variable=SST=6998.47\\ Step~9:~Variance~of~the~dependent~variable=SST/17\\ =6998.47/17=411.67$
