Practice Question
Which of the following statements is/are true?
(I) For each person, left-hand and right-hand gripping strength are dependent.
(II) For each person, left-hand and right-hand gripping strength are independent.
(III) In order to conduct a matched pairs test, we must assume that left-hand and right-hand gripping strength are both normally distributed.
(IV) In order to conduct a matched pairs test, we must assume that the differences in left-hand and right-hand gripping strength are normally distributed.
(A) II
(B) I and III
(C) I and IV
(D) II and III
(E) II and IV
Studdy Solution
Evaluate statement (IV): "In order to conduct a matched pairs test, we must assume that the differences in left-hand and right-hand gripping strength are normally distributed."
- The assumption required for a matched pairs test is that the differences between the paired observations are normally distributed. Therefore, statement (IV) is true.
Based on the analysis, the true statements are (I) and (IV).
The correct answer is:
