A 90% confidence interval for μ₁ − μ₂ using the sample results x̅₁ = 10.1, s₁ = 2.3, n₁ = 50 and x̅₂ = 12.4, s₂ = 5.7, n₂ = 50

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.
