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 sample mean 92.0 94.0 sample standard 2.0 1.5 deviation sample size 12 10 Determine the computed p-value to test whether to reject the null hypothesis of equal variance of the average yield from using catalyst A and B at a 5 % level of significance.
