Question: A 95% confidence interval for a difference in means 1 2 if the samples have n 1 = 100 with x 1

A 95% confidence interval for a difference in means μ₁ − μ₂ if the samples have n₁ = 100 with x̅₁ = 256 and s = 51 and n₂ = 120 with x̅ = 242 and s = 47, and the standard error is SE = 6.70

Find the indicated confidence interval. Assume the standard error comes from a bootstrap distribution that is approximately normally distributed.
