Problem 9E

An article in the Tappi Journal (March 1986) presented data on green liquor Na2S concentration (in grams per liter) and paper machine production (in tons per day). The data (read from a graph) follow: (a) Fit a simple linear regression model with y = green liquor Na2S concentration and x = production. Find an estimate of σ2. Draw a scatter diagram of the data and the resulting least squares fitted model.

(b) Find the fitted value of y corresponding to x = 910 and the associated residual.

(c) Find the mean green liquor Na2S concentration when the production rate is 950 tons per day.
