Use the t-distribution to find a confidence interval for a difference in means μ₁ - ₂ 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. A 99% confidence interval for μ₁ - ₂ using the sample results ₁ = 505, s₁ = 111, n₁ = 380 and ₂ = 424, s₂ = 91, n₂ = 200 Enter the exact answer for the best estimate and round your answers for the margin of error and the confidence interval to two decimal places. Best estimate i Margin of error = i Confidence interval: i to i
