Suppose we have taken independent, random samples of sizes ₁7 and n₂8 from two normally distributed populations having means ₁ and μ₂, and suppose we obtain 1 = 229, 2= 190. 16, 52 6. Use critical values to test the null hypothesis He: #1 #2 S 28 versus the alternative hypothesis Ha: #1 #2> 28 by setting a equal to 10, .05, 01 and .001. Using the equal variance procedure, how much evidence is there that the difference between ₁ and 4₂ exceeds 28? (Round your answer to 3 decimal places.) HO at a = 0.1, 0.05, and, 0.01 extremely strong no strong very strong evidence.
