Assume that you have a sample of n₁ =4, with the sample mean X, = 44, and a sample standard deviation of S₁ = 6, and you have an
independent sample of n₂=7 from another population with a sample mean of X₂ = 38 and the sample standard deviation S₂ = 7. Assuming
the population variances are equal, at the 0.01 level of significance, is there evidence that μ, >₂?
Find the test statistic.
