Final Answer : A, Explanation :  A one-sided test is used to test a specific direction of the alternative hypothesis, such as looking for an increase or decrease in a parameter. A two-sided test is used when the alternative hypothesis is simply that there is a difference between the groups, without specifying a direction. Since the question specifically asks for a difference in one direction, a one-sided test is appropriate.

A) one-sided test
