Question

Suppose we have taken independent, random samples of sizes n1 = 7 and n2 = 6 from two normally distributed populations having means µ1 and µ2, and suppose we obtain x¯1  = 240 , x¯2  =  208 , s1 = 5, s2 = 5. Use critical values to test the null hypothesis H0: µ1 − µ2 < 22 versus the alternative hypothesis Ha: µ1 − µ2 > 22 by setting α equal to .10, .05, .01 and .001. Using the equal variance procedure, how much evidence is there that the difference between µ1 and µ2 exceeds 22? (Round your answer to 3 decimal places.)

Use critical values to test the null hypothesis H₀: µ₁ − µ₂ < 22 versus the alternative hypothesis H_a: µ₁ − µ₂ > 22 by setting α equal to .10, .05, .01 and .001. Using the equal variance procedure, how much evidence is there that the difference between µ₁ and µ₂ exceeds 22? (Round your answer to 3 decimal places.)
