Three catalysts were compared to investigate how they affect the strength of a compound. When catalyst A was used 8 samples of the compound were obtained and the strengths of these 8 samples had a sample average of 42.91 and a sample standard deviation of 5.33. When catalyst B was used 11 samples of the compound were obtained and the strengths of these 11 samples had a sample average of 44.03 and a sample standard deviation of 4.01. When catalyst C was used, 10 samples of the compound were obtained and the strengths of these 10 samples had a sample average of 43.72 and a sample standard deviation of 5.10. Construct an analysis of variance table. Is there sufficient evidence to conclude that there is a difference between the three catalysts in terms of the strength of the compound?
