Estimate an appropriate simple regression that you can use to test whether mean mental ability scores of black infants are lower than those of white infants. Generate a table that you will use to report all your regression results (you may call the table "Regression results" or similar). Report the results of this simple regression in the first column of this table. (i) Interpret the constant and the slope of the regression. (ii) Interpretthe two goodness of fit measures discussed in the modules. (iii) Do the test mentioned above by following the six steps of hypothesis testing and stating any assumptions you make
