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 - M₂, the margin of error, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed. A 95% confidence interval for μ₁-₂ using the sample results ₁ = 74.7, s₁ = 10.8, n₁ = 35 and x₂ = 61.7, s₂ = 7.0, n₂ = 20 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
