Question: A 95% confidence interval for 1 2 using the sample results x 1 = 75.2, s 1 = 10.7, n 1 =

A 95% confidence interval for μ₁ − μ₂ using the sample results x̅₁ = 75.2, s₁ = 10.7, n₁ = 30 and x̅₂ = 69.0, s₂ = 8.3, n₂ = 20

Use the t-distribution to find a confidence interval for a difference in means μ₁ − μ₂ given the relevant sample results. Give the best estimate for μ₁ − μ₂, the margin of error, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed.
