Assume that you have a sample of n₁ = 7, with the sample mean X₁ = 45, and a sample standard deviation of S₁ = 5, and you have an independent sample of n₂ = 5
from another population with a sample mean of X₂ = 31 and the sample standard deviation S₂ = 6. Assuming the population variances are equal, at the 0.01 level of
significance, is there evidence that μ₁ > ₂?
