The life lengths of four different brands of light bulbs are being compared. The results follow: 3.1 Set up the linear model and find the normal equations. 3.2 Solve the normal equations by using the constraint α1​+α2​+α3​+α4​=0 where αi​ is the effect of the ith  brand. 3.3 Which generalized inverse corresponds to the use of the constraint in part (3.2)? 3.4 Construct the ANOVA table. 3.5 By formulating appropriate constraints and testing hypotheses about them, determine whether there is a statistically significant difference between the average life length of 3.5.1 A and C. 3.5.2 B and C. 3.5.3 C and D. 3.5.4 The average of A, B and the average of C and D.
