Question 1a Red wine, in moderation, has been thought of as heart healthy. Suppose that you want to test whether red wine was associated with a reduction in the risk of heart attacks. Consider the following regression model: y = Bo+Px + u You are going to run regression using a survey dataset. If y; is individual f's health (a higher score indicates better health conditions) and x is the individual's red wine consumption (given a period of time), what is included in u [Blank 1]? (list at least one) what sign of bias would you expect in an OLS regression of y on x [Blank 2]? (enter "positive" or "negative") Blank # 1 Blank # 2
