Answer to Question 1

ANS: A
The chi-square () test compares differences in proportions of nominal level variables. A two-way chi-square is a statistic that tests whether proportions in levels of one variable are significantly different from proportions of the second variable. In other words, it detects whether one nominal variable seems to be related to another one.

Answer to Question 2

ANS: C, E, F
Logistic regression replaces linear regression when the researcher wants to test a predictor or predictors of a dichotomous dependent variable. Logistic regression can have continuous predictors or nominal predictors or a combination of the two, with no assumptions regarding normality of the distribution.
