(a)State the degrees of freedom for theFtest for overall significance.

The degrees of freedom for regression are?and for error?.

(b)UseAppendix Fto look up the critical value ofFfor= .05.(Round your answer to 2 decimal places.)

F_.05?

(c-1)Calculate theFstatistic.(Round your answer to 4 decimal places.)

(c-2)The overall regression is significant.

• No
• Yes

1. (c-3)The hypotheses is

a. H₀: All the coefficients are zero (₁=₂=₃= 0) vs.H₁: At least one coefficient is not zero.
