Question 1 of 14 -/1 View Policies Current Attempt in Progress Use a t-distribution to find a confidence interval for the difference in means Ha = H1 - H2 using the relevant sample results from paired data. Assume the results come from random samples from populations that are approximately normally distributed, and that differences are computed using d = x1 – x2. A 95% confidence interval for 4a using the paired difference sample results d = 2.1, Sd = 2.4, na = 30. Give the best estimate for u, the margin of error, and the confidence interval. Enter the exact answer for the best estimate, and round your answers for the margin of error and the confidence interval to two

Current Attempt in Progress
Use a t-distribution to find a confidence interval for the difference in means uj = µ1 - H, using the relevant sample results from
paired data. Assume the results come from random samples from populations that are approximately normally distributed, and that
differences are computed using d
= x1 – X2.
