Key Points

The correct matching is as follows:

List I	List II
A. Reject Ho when it is true	Type - I error
B. Accept Ho when it is not true	Type - II error
C. Probability of rejecting H0, when it is true	Level of significance
D. Probability of rejecting H0, when it is not true	Power of test

Type I error is the probability of rejecting the null hypothesis when it is true. This is also known as the alpha error.
Type II error is the probability of accepting the null hypothesis when it is not true. This is also known as the beta error.
Level of significance is the probability of committing a Type I error ( rejecting H0, when it is true). It is typically set at 0.05 or 0.01.
Power of test is the probability of rejecting the null hypothesis when it is false. It is also known as the 1-beta.

Therefore, the answer is 3) A-II, B - III, C - IV, D - I.

LIST I		LIST II
A.	Reject H_o when it is true	I.	Power of test
B.	Accept H_o when it is not true	II.	Type - I error
C.	Probability of rejecting H₀, when it is true	III.	Type - II error
D.	Probability of rejecting H₀, when it is not true	IV.	Level of significance
