Given are five observations for two variables, x and y.

xi

1 2 3 4 5

yi

3 8 5 10 14

(d)

Develop the estimated regression equation by computing the values of b0 and b1 using b1 =

Σ(xi − x)(yi − y)
Σ(xi − x)2

and b0 = y − b1x.

ŷ =

(e) Use the estimated regression equation to predict the value of y when x = 2.

b0 = 0.8

b1 = 2.4

\hat y = 0.8 + 2.4 x

Predicted value = 5.6
