(a) Draw a scatter diagram to show a possible association between the infant mortality rate (used as the dependent variable) and the net food supply and check to see if a linear model is justified.
(b) Estimate the regression parameters, the infant mortality rate for a country with a net food supply of 2900 calories per person per day, and draw the regression line on the same graph with the scatter diagram.
(c) Test to see if the two factors are independent; state your hypotheses and choice of test size.
(d) Calculate the coefficient of determination and provide your interpretation.
