Assume that you have a sample of n₁ =9, with the sample mean X₁ = 47, and a sample standard deviation of S₁ = 4, and you have an independent sample of n₂ = 17 from another population with a sample mean of X₂ = 35, and the sample standard deviation S₂ = 5. Construct a 95% confidence interval estimate of the population mean difference between μ₁ and µ₂. Assume that the two population variances are equal. ≤μ₁-H₂ ≤ (Round to two decimal places as needed.)
