Use the t-distribution to find a confidence interval for a difference in means -given the relevant sample results. Give the best estimate for - , 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 - M using the sample results x = 9.8, s = 2.2, n = 50 and x2 50 and x2 = 12.3, s = 12.3, s = 6.1, n = 50 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 - 1 Margin of error = i Confidence interval: i to i 13 Use the t-distribution to find a confidence interval for a difference in means -given the relevant sample results.
