The American Ceramic Society Bulletin (Feb. 2005) study of bricks that line aluminum smelter pots, You fit the simple linear regression model relating brick porosity (y) to mean pore diameter (x) to the data in the SMELTPOT file.
a. Find an estimate of the standard deviation s of the model.
b. In Exercise, you predicted brick porosity percentage when x = 10 micrometers. Use the result of part a to estimate the error of prediction.
