ISYE 6414 Midterm Prep Questions and Answers Graded A+ 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 corresponding means are plausibly equal. True The assumption of normality is not required in linear regression to make inference on the regression coefficients. False (Explanation: is required) We cannot estimate a multi...
