Use thet-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=5.1, s1=2.6, n1=11 and x¯2=4.8, s2=2.7, n2=8


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 = Enter your answer; Best estimate


Margin of error = Enter your answer; Margin of error
