<em>It may seem that the options have been omitted in this question. However, in order to evaluate the claim that a mean from a particular group is statistically higher or lower to a mean from another group, there would be a need to compare the two means. </em>
Mean comparison or testing for a significant difference between means can be carried out using the Student's t-test or one-way Analysis of Variance (ANOVA).
When the means being compared are just for 2 groups as indicated in the illustration, Student's t-test and one-way ANOVA can be used. However, once there are more than 2 group means being compared, one-way ANOVA will only be applicable.
