To study the effect of temperature on yield in a chemical process, four batches were produced at each of three temperature levels. The results follow. Construct an analysis of variance table. State the Hypotheses. Use a .05 level of significance to test whether the temperature level has an effect on the mean yield of the process. Use both p-Value and Critical-Value approaches.
