Below is the data on consumption expenditures, consumption, disposable income, and sex of the head of household of 12 randomly chosen families. The variable gender has been coded as gender = {1 if sex = male; 0 if sex = female}. Develop a multiple regression model for each of the independent variable to predict consumption. Comment on its regression coefficients, R-square and Multiple R. Interpret the p-value in terms of strength of the variables used in the model.
