Two catalysts are being analyzed to determine how they affect the average yield of the chemical process. The higher the yield in percentage, the better the catalyst is. Catalyst A is a commercial catalyst that is currently being used. Catalyst B is developed by our research group based on a geopolymer material. The following table is the summarized result from the test runs in the pilot plant. Based on the normal probability plot, it is valid to assume normal distribution from these data. A B sample mean 92.0 94.0 sample standard 2.0 1.5 deviation sample size 12 10 Would there be any difference in the average yield at a 5 % level of significance? Is it valid to assume equal variances at a 5 % level of significance? Show the solution using statistical inference based on hypothesis testing by filling in the blanks. Express your numerical answers in 2 decimal places (e.g., 0.23, 0.01, or -2.10) unless specified and choose the right words as suggested in < text1, text2 >
