IRISSAK [1]

Answer:

See the answer below

Explanation:

<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>
