Current Attempt in Progress Use the t-distribution to find a confidence interval for a difference in means ₁-₂ given the relevant sample results. Give the best estimate for ₁-₂, the margin of error, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed. A 90% confidence interval for ₁-₂ using the sample results ₁ = 78.6,5₁ = 11.6.n,=25 and ₂ = 65.7.2= 7.0, m₂ = 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: to
