Question: Given are five observations for two variables, x and y . x i 1 2 3 4 5 y i 3 8 5 11 13

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

xi

 1 2 3 4 5

yi

 3 8 5 11 13

(d)Develop the estimated regression equation by computing the values of

b0 and b1 using b1 =

(xi x)(yi y)
(xi x)2

and

b0 = y b1x.

=

(e)Use the estimated regression equation to predict the value of y when x = 4.
