Use the t-distribution to find a confidence interval for a difference in means μ1-μ2 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 95% confidence interval for μ1-μ2 using the sample results x¯1=9.4, s1=2.2, n1=50 and x¯2=13.4, s2=5.2, n2=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 = ?
Margin of error = ?

Confidence interval :?
