Hi,

Thank you for using JustAnswer, and thank you for requesting me.

Here are the solutions:

1. B

2. C

3. It's either B or D, depending on the scope of "regression analysis". My first choice would be D, since the "regression analysis" generates the equation that is subsequently used to make predictions. Once you have the equation, the analysis is done, so "the independent variable is used to predict the dependent variable" really isn't included in the regression analysis. If choice D is rejected, then the next choice is B.

4. C


Thanks,

Ryan
