    Downs and Abwender (2002) evaluated soccer players and swimmers to determine whether the routine blows to the head experienced by soccer players produced long-term neurological deficits. In the study, neurological tests were administered to mature soccer players and swimmers and the results indicated significant differences. In a similar study, a researcher obtained the following data

    Swimmers: 10, 8, 7, 9, 13, 7, 6, 12
    Soccer Players: 7, 4, 9, 3, 7

    a) Are the neurological test scores significantly lower for the soccer players than the swimmers in the control group? Use a one-tailed test with and alpha =.05

    b) Compute the value of r (sqr) (percentage of variance accounted for) for these data.

    Please use all standard mathematical calculations.
