(You have two attempts for this question) In multiple regression, each slope can be interpreted as (choose one): Q The prediction of the response variable when that predictor is O. O The predicted change in the response variable for a one unit increase in that predictor variable, while holding all other predictor variables constant. 0 The proportion of variability in the response that is explained by that predictor variable, while holding all other predictor variables constant 0 The prediction of the response variable when that predictor is 0, while holding all other predictor variables constant. 0 The predicted change in the response variable for a one unit increase in that predictor variable. (Hypothetical) A researcher found that as the proportion of people who filed their taxes jointly dropped, the divorce rate (number of divorces per 1000 people) dropped as well. (Note: Filing taxes jointly is an option for married couples.) The researcher concluded that filing taxes jointly caused divorce and now advises couples to file separately. Explain how the number of new marriages is a confounding variable. (You have two attempts for this question) O As more people get married, the proportion of people who file taxes jointly will drop. As more people get married, the divorce rate will drop. Thus, as fewer people file their taxes jointly, the fewer people will get divorced. As fewer people get married, the proportion of people who file taxes jointly will drop. As fewer people get married, the divorce rate will drop. Thus, as fewer people file their taxes jointly, the fewer people will get divorced. As fewer people get married, the proportion of people who file taxes jointly will drop. As fewer people get married, the divorce rate will drop. Thus, as fewer people file their taxes jointly, the more people will get divorced. As fewer people get married, the proportion of people who file taxes jointly will drop. As fewer people get married, the divorce rate will increase. Thus, as fewer people file their taxes jointly, the fewer people will get divorced. As fewer people get married, the proportion of people who file taxes jointly will increase. As fewer people get married, the divorce rate will drop. Thus, as fewer people file their taxes jointly, the fewer people will get divorced
