A researcher tested whether aerobics increased the fitness levelof eight undergraduate students participating over a 4-monthperiod. Students were measured at the end of each month using a10-point fitness measure (10 being most fit). The data are shownhere. Conduct an ANOVA to determine the effectiveness of theprogram, using alpha = .05. Use the Bonferroni method to detectexactly where the differences are among the time points (if theyare different).
