Question 5

Does the population mean rings score depend on the age of the gymnast? Consider the three age groups: 11-13, 14-16, and 17-19. Use the results from the 2007, 2011, and 2015 Individual Male All-Around Finals as sample data.

a) Perform at the 10% significance level the one-way ANOVA test to compare the population mean rings scores for each of the three age groups assuming that all of the requirements are met. Should we reject or not reject the claim that there is no difference in population mean scores between the age groups?

b) Provide a possible explanation for the difference you did or did not observe in mean scores between the age groups in part a).
