On a radio show, an official reported that people who have more children get divorced less often. Because of this, the official argued that people should have more kids to help strengthen their marriage.

C. Design a regression study that will test whether this third variable of the burden of child support after a divorce accounts for the correlation between number of children and divorce. What are the independent and dependent variables in your model? There are at least two possible results (when controlling for the third variable, the number of children no longer predicts divorce, or when controlling for the third variable, the number of children still predicts divorce). Draw each one, using circles to represent each variable. Estimate some betas that you would expect to find if each of the two patterns turns out to be the case. Write a sentence that represents each of the three possible results using the words controlling for.
