1. You wish to test whether the average FEV1 for athletes in aerobic sports is different than non-aerobic sports. You sample 25 athletes from each group with the following results Xbar aerobic = 3.5 SD = 0.2.Xbar non-aerobic = 3.3 SD = 0.2.Propose a null and alternative hypothesis for your analysis. What statistical test should you apply? Calculate that statistic and the associated p value. With an alpha = 0.05 can you reject your null hypothesis and accept the alternative.
