Do the following problems from Montgomery & Runger, Applied Statistics and Probability for Engineers, 2nd edition. Practice using your calculator accurately and efficiently. For each question, you should also find a 95% confidence interval for the residual variance s2.
I will post model solutions for these questions.
12-1 (a, b). Also, analyse these data as a simple linear regression, breaking SSE from the regression ANOVA into SSLOF and SSPE in order to test the assumption of linearity.
12-2 (a), 12-3 (a, b).
13-1 (a), 13-2 (a), 13-3 (a, b).
