Case 3 4 5 Treatment 1 22 28 31 25 Treatment 2 28 18 30 25 21 21

Use a t-distribution to find a confidence interval for the difference in means Î¼₁ ˆ’ Î¼₂ using the relevant sample results from paired data. Give the best estimate for Î¼₁ ˆ’ Î¼₂, the margin of error, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed, and that differences are computed using d = x₁ ˆ’ x₂.
