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 −μ₂ using the sample results ₁ = 545,₁ 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 = 109, n₁ = 360 and ₂ = 451, s₂ = 96, n₂ = 200
