      The corresponding test statistics are 89.09 and -52.10 indicating that these are too large values of t-statististics and lie on the extreme ends of t-curve. Thus we reject the null hypothesis of alpha =o and beta=o. And conclude that the beta and alpha play a significant role in the regression model. S = 2.94921 R-Sq = 99.5% R-Sq(adj) = 99.5%
