Suppose we have taken independent, random samples of sizes n₁ = 7 and n₂ = 7 from two normally distributed populations having means ₁ and ₂, and suppose we obtain x1x1 = 240, x2x2 = 210, s₁ = 5, s₂ = 6.

Assuming equal variances calculate a 95 percent confidence interval for _{1 2}. Can we be 95 percent confident that _{1 2} is greater than 20?(Round your answers to 3 decimal places.)
