We want to test whether or not the addition of 3 variables to a model will be statistically significant. You are given the following information based on a sample of 25 observations. 
= 62.42 - 1.836x1 + 25.62x2
SSE = 725 SSR = 526
The equation was also estimated including the 3 variables. The results are 
= 59.23 - 1.762x1 + 25.638x2 + 16.237x3 + 15.297x4 - 18.723x5
SSE = 520 SSR = 731
