A 99% confidence interval for μ₁ˆ’ μ₂using the paired data in the following table:

Use a t-distribution to find a confidence interval for the difference in means μ₁ ˆ’ μ₂ using the relevant sample results from paired data. Give the best estimate for μ₁ ˆ’ μ₂, 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.
