Explanation / Answer
1. C. Level of significanc
The term significance level (alpha) is used to refer to a pre-chosen probability and the term "P value" is used to indicate a probability that you calculate after a given study.
2. C. Multicollinearity
Multicollinearity refers to a situation in which two or more explanatory variables in a multiple regression model are highly linearly related.
