ANOVA (Analysis of Variance) is the proper statistical test in this scenario as it is used to compare the means of three or more groups. It examines whether there is a significant difference between the means of the groups, taking into account the variability within each group. The other options listed are not appropriate for comparing the means of multiple groups.
