Given a sample of n 1 =18 from a population with s 1 = 13.5, and an independent sample of n 2 =28 from another population with s 2 =11.8, what is the value of the t test statistic for testing H 0: µ 1 = µ 2 at ? = 0.01 if ? 1 = 64.2 and ? 2 = 69.1?

Given a sample of ni =18 from a population with si = 13.5, and an independent sample of n2 =28 from another population with s2 =11.8, what is the value of the t test statistic for testing Ho: Hi = P2 at a = 0.01 if X, = 64.2 and X2 = 69.1? Solution: Step 1: State the hypothesis Ho: . Hi: Step 2: The level of significance and critical region, a = _, df = Step 3: Compute for the value of t test. and teritical = tcomputed = Step 4: Decision rule. Step 5: Conclusion.
