3. (6 points) The dataset BWGT contains data on births to women in the United States. Two variables of interest are the dependent variable, infant birth weight in ounces (bwght), and an explanatory variable, the average number of cigarettes the mother smoked per day during pregnancy (cigs). The following simple OLS regression was estimated using data on n=1,388 births: bwgt = 119.77 – 0.514cigs What is the predicted birth weight when cigs=0? What about when cigs=20 (one pack per day)?...

Question 3 A researcher is interested in the relationship between the birth weights of infants and mothers' smoking habits. He uses the birth weight of an infant (ounces) and the average number of cigarettes the mother smokes per day during the pregnancy as the dependent and independent variables, y and x, respectively. Using a sample of size (1388 the following model is obtained by the method of least squares: y-119.770.514.x (3.15) (0.13) SE e the figures in brackets are the...
