faminci: monthly income of the family of infant i (RM1000s). a. What are your expectations about the signs of 1 and 2 , respectively? Explain your answer. (5 points) b. The EViews data file health contains data for the variables. Estimate the model using OLS method. Present/display the EViews regression result. c. Interpret the estimated coefficient of faminc that you obtained in b d. Interpret the adjusted R-squared value obtained. e. Test whether your expectation about 1 is supported/not, based on the empirical results obtained.
