To explain: The reason of using the two-sample t procedure when the procedure is robust.
Explanation of Solution
Given:
The test procedure is robust.
The term robust implies that the result of the test would be appropriate even if the required assumptions for the test are not simplified.
The important assumption for the two-sample t procedure is the normality. Robust two sample procedure implies the result of the test would be accurate even if the normality assumption of the test is not satisfied because t procedure is applicable even if the distribution is not
Thus, the correct option is (d).
