The study involving the 5 children followed the children for two years. As part of the study, children were weighed when they were four and again when they were six. Table shows the results, including the children's weight gain over the two-year period (Difference). Weight Age 4 (Ibs) Weight Age 6 (Ibs) Difference (Ibs) 37.1 46.9 9.8 26.7 35.9 9.2 36.1 48.3 12.2 36.2 44.2 8.0 40.3 50.6 10.3 In the past, children around this age would have been expected to gain 9 pounds over the two-veer period. However, we suspect that the mean change in weight has increased. What is the most appropriate test? A. Chi-square test Paired t-test C. Unpaired t-test D. ANOVA test E.
