In a Multiple Regression Problem Involving 24 Observations and Three $\hat { y }$

question 118

True/False

In a multiple regression problem involving 24 observations and three independent variables, the estimated regression equation is $\hat { y }$ = 72 + 3.2x1 + 1.5 x2 - x3. For this model, SST = 800 and SSE = 245. The value of the F-statistic for testing the significance of this model is 15.102.
