Chapter 12, Problem 12.12.8(choose chapter or problem)
In a simple linear regression analysis with n =20 data points, the estimates 0 =123.57, 1 = 3.90, and =11.52 are obtained, with20 i=1 xi =856, 20 i=1 x2 i =37,636,20 i=1 yi =869, and 20 i=1 y2 i =55,230. (a) Construct a two-sided 95% prediction interval for a future response value when the input value is 40. (b) Compute the analysis of variance table and calculate the coefcient of determination R2.
