2. 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) are shown as follows: y 40 42 49 46 44 48 825 830 890 895 890 910 y 46 43 53 52 54 57 58 915 960 990 1010 1012 1030 1050 (a) Fit a simple linear regression model with y green liquor Na2S concentration and x production. 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.
