Question 17
Correct Answer:
To compare the sales between GrpA and GrpB, you can use a t-test or analysis of variance (ANOVA). In SAS, the `proc ttest` and `proc glm` procedures are suitable for these purposes. The correct programs are the following: A and C. Response A uses the `proc ttest`, which directly compares the means of two groups specified by the `class` statement. Response C employs the `proc glm` for ANOVA, where the class statement is used to define the categorical variable (Region), and the model specifies the relationship between sales and region. Option B is incorrect as it wrongly uses the `model` statement with `proc ttest`, and option D is also incorrect because it specifies the `class` statement improperly for a continuous variable like Sales. Therefore, the correct answers are A and C.

These questions have so many errors... A,C should be correct answers.

Answer should be A,C. In PROC TEST there is no model.

A and C are correct. In B the ttest proc is using the model keyword, which is wrong
