Researchers conduct a study to determine the effect of a year-long aerobic exercise program on cardiovascular health. They measured cholesterol levels in a group of adults at the beginning and at the end of the program. To analyze the differences in cholesterol levels over the study period within the same group of participants, which statistical test is most appropriate to handle the paired data generated from these repeated measures? 9 a. Dependent sample t-test, because it allows comparison between different groups over time. b. Dependent sample t-test, because it compares means from the same group at different times. C. ANOVA (Analysis of Variance), because it allows comparing means from more than two groups or categories. d. Independent samples t-test, because the measurements involve different time points
