Current Attempt in Progress Use the t-distribution to find a confidence interval for a difference in means / - /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 95% confidence interval for 1 - /2 using the sample results .71 = 80.6, s; = 12.0. m, = 30 and X2 = 68.7, s, = 7.9, n = 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 e Textbook and Media Save for Later Attempts: 0 of 3 used Submit
