Question

Consider the following hypothesis test.

H₀: ?₁² = ?₂²

H_a: ?₁² ≠ ?₂²

(a) What is your conclusion if n₁ = 21, s₁² = 4.2, n₂ = 26, and s₂² = 2.0?

Use ? = 0.05 and the p-value approach.

Find the value of the test statistic: _______

Find the p-value. (Round your answer to four decimal places.) p-value = ___________

State your conclusion.

A) Reject H₀. We cannot conclude that ?₁² ≠ ?₂².

B) Do not reject H₀. We cannot conclude that ?₁² ≠ ?₂².

C) Reject H₀. We can conclude that ?₁² ≠ ?₂²

^D).Do not reject H₀. We can conclude that ?₁² ≠ ?₂².

(b)Repeat the test using the critical value approach.Find the value of the test statistic.

State the critical values for the rejection rule. (Round your answers to two decimal places. If you are only using one tail, enter NONE for the unused tail.)

test statistic ≤ _________

test statistic ≥ _____

State your conclusion.

A) Reject H₀. We cannot conclude that ?₁² ≠ ?₂².

B) Do not reject H₀. We cannot conclude that ?₁² ≠ ?₂².

C) Reject H₀. We can conclude that ?₁² ≠ ?₂².

D) Do not reject H₀. We can conclude that ?₁² ≠ ?₂².
