We can assess the constant variance assumption in linear regression by plotting the residuals vs. fitted values. - Answer- True If one confidence interval in the pairwise comparison in ANOVA includes zero, we conclude that the two corresponding means are plausibly equal. - Answer- True The assumption of normality is not required in linear regression to make inference on the regression coefficients. - Answer- False (Explanation: is required) We cannot estimate a multiple linear regressio...

The number of degrees of freedom of the χ 2 (chi-square) distribution for the pooled variance estimator is N − k + 1 where k is the number of samples. - False If the confidence interval for a regression coefficient contains the value zero, we interpret that the regression coefficient is definitely equal to zero. - False. The coefficient is plausibly zero, but we cannot be certain that it is If one confidence interval in the pairwise comparison in ANOVA includes zero, we conclude that the...
