K A sports reporter suggests that professional baseball players must be, on average, older than professional football players, since football is a contact sport. Researchers selected 35 professional football players and 33 professional baseball players at random. The data collected are summarized by the accompanying table. Suppose the researchers decide to test the hypothesis. The degrees of freedom formula gives 56.25 df. Test the null hypothesis at x = 0.05. A. Ho: H₁-H₂ = 0 HA: H1 H₂0 O C. Ho: Hi-H2 = 0 HA: H1 H₂ <0 Compute the test statistic. ... Let μ₁ be the mean age of professional baseball players and let μ₂ be the mean age of professional football players.
