  • Abstract:

    The datafile contains 1991 season leading quarterback and total team salary
    for football teams in the American Football Conference (AFC) and National
    Football Conference (NFC) of the National Football League(NFL). Two poten-
    tial influential observations (Steelers and Bears) are present. They are the 
    high X-observations in the scatter diagram shown below. The student should
    try the regression with and without these teams to see if their inclusion or ex-
    clusion makes a material difference. 

    The two conferences are distinguished in the scatter diagram. The student 
    should test if the same regression (average level and slope) applies equally
    to the two conferences.
