Question

What is the rejection region in a two-tailed hypothesis test with a significance level of 0.01?

A) the upper 1% of the distribution
B) the lower 1% of the distribution
C) the upper and lower 0.5% of the distribution
D) the upper and lower 1% of the distribution

Answer 1

• Answer:

OPTION (C): The REJECTION REGION is the UPPER and LOWER (0.5%) of the Distribution.

• Explanation:

Make A Plan: Choose the Correct Option:

Understand The Concept:

In a Two-Tailed Hypothesis Test, The rejection region is divided equally between the two tails of the distribution.

• Solve the problem:

Calculate the Rejection Region:

Since the significance level is (0.01), We need to divide it by 2 to find the rejection region for each tail.

0.01 / 2 = 0.005

• Draw the conclusion:

Choose the correct option

OPTION (C): The REJECTION REGION is the UPPER and LOWER (0.5%) of the Distribution.

The Final Answer is OPTION (C).

I hope this helps!
