Chapter 10

Suppose we have taken independent, random samples of sizes n₁ = 7 and n₂ = 7 from two normally distributed populations having means ₁ and ₂, andsuppose we obtain , , s₁ = 6, s₂ = 6. Use critical values to test the null hypothesis H₀: _{1 2}< 35 versus the alternative hypothesis H_a: _{1 2} > 35 by setting equal to .10, .05, .01 and .001. Using the equal variance procedure, how much evidence is there that the difference between ₁ and ₂ exceeds 35? (Round your answer to 3 decimals)
