ANOVA

The next four questions refer to the following scenario:

You want to look at an ANOVA table of a regression in which a dependent variable is predicted using an intercept and one slope coefficient. Unfortunately, as you want to look at the table, you knock over your coffee mug which smudges out some of the numbers. Here is what you still can read:

n=7

F-ratio = 10

Residual sum of squares (RSS) = 25

t-score for the slope coefficient = 2.571
