Question Answered step-by-step Use the tdistribution to find a confidence interval for a… 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, the relevant degrees of freedom, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed. A 90% confidence interval for µ1 − µ2 using the sample results ¯x1 = 10.1, s1 = 2.3, n1 = 50, and x¯2 = 12.4, s2 = 5.7, n2 = 50. Note that here t ∗ = 1.677.
