Suppose that you were interested in studying the effect of temperature on the yield of a chemical process, and that 3 batches were produced at each of three temperatures, producing the following table of data: (with 45C = Treatment 1; 55C = Treatment 2; and 65C = Treatment 3) 45C 55C 65C 35 22 30 37 26 29 31 23 31 Excel was used to run the Single-Factor ANOVA procedure on this data with alpha = 5%, and the results follow. Use the provided Excel-generated results to answer the following questions. Give exact values.
