2. Two catalysts may be used in a batch chemical process. Twelve batches were prepared using catalyst 1, resulting in an average yield of 86 and a sample standard deviation of 3. Fifteen batches were prepared using catalyst 2, and they resulted in an average yield of 89 with a standard deviation of 2. Assume that yield measurements are approximately normally distributed with the same standard deviation. Is there evidence to support a claim that catalyst 2 produces a higher mean yield than catalyst 1? Use alpha 0.01. Let the yield measurements from catalyst 1 represent population 1. Let the yield measurements from catalyst 2 represent population 2. A. The appropriate alternative hypothesis for this test is:_ B. The critical value is 4.00.) (Write your answer precise to 3 decimal places, e.g. 2.45, 3.01, C. The pooled sample variance is equal to C. The test statistic is D. The p-value is equal to E. The correct decision is to (reject or not reject) Ho. F. The correct conclusion is that there is (significant or insignificant) sample evidence to show that the mean yield produced by catalyst 2 is (higher or not higher) than the mean yield produced by catalyst 1.
