1 )True or False? Refer to this ANOVA table from a multiple regression (some information is missing but can be worked out). There were 5 predictors in the regression model (note: the constant term in the model for the intercept is not a predictor).

2) Based on the table above, there are ____ observations in the sample
a. 50
b. 49
c. 60
d. 45
3) Based on the table above, True or False, the SSE is equal to 2695.0996
4) Based on the table above, the MSE is equal to
a. 60.941
b. 325.142
c. 448.309
d. 106.478
5) Based on thee table above, the F statistics is equal to 7.485
6) True or False? Based on the table above. In a righttailed test, we fail to reject the null hypothesis all the predictors are zero at ? = 0.05, by comparing the F statistic for the overall fit with the critical value F4,45 which is 2.58.
