The null and alternative hypotheses for a test are given as well as some information about the actual sample(s) and the statistic that is computed for each randomization sample. Indicate where the randomization distribution will be centered. In addition, indicate whether the test is a left-tail test, a right-tail test, or a two tailed test.

Hypotheses: H₀: μ₁ = μ₂ vs H_a: μ₁ ≠ μ₂
Sample: x̅₁ = 2.7 and x̅₂ = 2.1
Randomization statistic = x̅₁ − x̅₂
