talysts may be emical process. Twelve batches were prepared using catalyst 1, resulting a sample standard deviation of 3. Fifteen batches were prepared using catalyst 2, and they resulted in an av standard deviation of 2. Assume that yield measurements are approximately normally distributed with the s on. ere evidence to support the claim that catalyst 2 produces higher mean yield than catalyst 1? Use α = 0.01 la 99% confidence interval on the difference in mean yields that can be used to test the claim in part (a). Rou cimal places (e.g. 98.76). 2 ≤ i
