The amount of catalyst (x) and the yield (y) of a chemical
Chapter 12, Problem 12.5.8(choose chapter or problem)
The amount of catalyst (x) and the yield (y) of a chemical experiment are analyzed using a simple linear regressionmodel. There are 30 observations (xi, yi), and it is found that the tted model is y =51.98+3.44x Suppose that the sum of squared residuals is 30 i=1 e2 i =329.77, and that30 i=1 xi =603.36, 30 i=1 x2 i =12578.22. If an additional experiment is planned with a catalyst level 22, give a range of values with 95% condence for the yield that you think will be obtained for that experiment.
