where outfield is the base group.
(i) State the null hypothesis that, controlling for other factors, catchers and outfielders earn, on average, the same amount. Test this hypothesis using the data in MLB1.RAW and comment on the size of the estimated salary differential.
(ii) State and test the null hypothesis that there is no difference in average salary across positions, once other factors have been controlled for.
(iii) Are the results from parts (i) and (ii) consistent If not, explain what is happening.
