Given below two statements, one is labelled as Assertion A and the other is labelled as

Reason R

Assertion A: Obtained t-valve will follow theoretical t-distribution if underlying assumptions are fulfilled

Reason R: The application of t-test makes an assumption of heterogeneity of variance

In light of the above statements, choose the most appropriate answer from the options given below:

1. ABoth A and R are correct and R is correct explanation of A
2. BBoth A and R are correct but R is NOT the correct explanation of A
3. CA is correct but R is not correct
4. DA is not correct but R is correct

Pick an option to check yourself, or open the answer below.

Show answer & explanation

Correct answer: C. A is correct but R is not correct

Explanation

Obtained t follows the t-distribution only if the assumptions hold, and one of them is homogeneity (not heterogeneity) of variance.
