Question: Consider the following computer output. The regression equation is Analysis of Variance (a) Fill in the missing information. You may use bounds for the P-values.

Consider the following computer output.

The regression equation is

Y = 12.9 + 2.34 x Predictor Constant x Coef SE Coef

Analysis of Variance

T 12.857 1.032 ? 2.3445 0.1150 ? 222 P ? ? S=1.48111

(a) Fill in the missing information. You may use bounds for the P-values.

(b) Can you conclude that the model defines a useful linear relationship?

(c) What is your estimate of σ2?

Y = 12.9 + 2.34 x Predictor Constant x Coef SE Coef T 12.857 1.032 ? 2.3445 0.1150 ? 222 P ? ? S=1.48111 R-sq=98.1% R-sq(adj) = 97.9%
