Refer to Exercise 18.

You have selected two random samples of size 50, one from Population 1 and one from Population 2. You intend to use the samples to test the following hypotheses regarding the difference in means for the two populations: H₀: μ₁ – μ₂ = 0 Ha: μ₁ – μ₂ ≠ 0

a. Compute the p-value for the sample result and explain what it means.

b. Use the p-value from part a to decide whether you will reject the null hypothesis. Explain your decision.
