Assume that you have a sample of n₁ = 6, with the sample mean X₁ = 49, 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 = 34 and the sample standard deviation S₂ = 5. Assuming the population variances are equal, at the 0.01 level of significance, is there evidence that H₁> H₂? Determine the hypotheses. Choose the correct answer below. OA. Ho: H1 H2 H₁: H1 H2 O C.
