We can assess the constant variance assumption in linear regression by plotting the residuals vs. fitted 
values. - True 
If one confidence interval in the pairwise comparison in ANOVA includes zero, we conclude that the two

Least Square Elimination (LSE) cannot be applied to GLM models. - False - it is applicable but does 
not use data distribution information fully. 
In multiple linear regression with idd and equal variance, the least squares estimation of regression 
coefficients are always unbiased. - True - the lea...
