Suppose we have taken independent, random samples of sizes n₁ =7 and n₂ = 7 from two normally distributed populations havingmeans ₁ and ₂, and suppose we obtain #₁ = 240, = 210, $₁ = 5, s2 = 6.Assuming equal variances calculate a 95 percent confidence interval for H₁ - H₂. Can we be 95 percent confident that μ₂-₂ isgreater than 20? (Round your answers to 3 decimal places.)The confidence interval=[Yesthe entire interval isaboveWhy we can use the equal variances procedure here?s1 and s2 very close and n1 = n2O s1 and s2 very close and n1 # n220
