1.I'm conducting a regression analysis in which I have several predictors I know to be correlated with one another. Which of the following assumptions of multiple regression am I likely in violation of?

A.Heteroskedasticity

B.Normality of the outcome

C.Multicollinearity

D.Homogeneity of Variance

2.True or False: You can add variables to a regression equation and raise the R-squared value but still not have any of the added variables be statistically significant.

3.True or False: When I add more variables to a regression equation, the amount of variance in the outcome variable increases.
