A dataset contains data on birth weights of 65535 babies born in June 1997 along with variables that are potentially related to birth weights. The sample is restricted to singleton births, with mothers recorded as either black or white, between the ages of 18 and 45, resident in the United States. With the aim to investigate factors influencing the weight of babies at birth, a regression of Weight on a range of variables has been carried out. A description of variables is given below and the estimation results can be found on the following page. Referring to these results, answer the following questions. Keep in mind that two of the regressors, Mom_Age and M_WtGain, are entered in the regression in terms of the deviations from their mean. (c) Would you say the fact that the mother is a smoker is an important determinant of the birth weight of the baby? (d) What is the expected difference in birth weight of babies whose mothers have a high school and babies whose mothers are college graduates, ceteris paribus? Explain your reasoning.
