10 5 20 5 9 To study the effect of temperature on yield in a chemical process, five batches were produced at each of three temperature levels. The results are found in the table below. Conduct an analysis of variance. Use a =0.05 level of significance to test whether the temperature level has an effect on the mean yield of the process. What is your p-value and what is your conclusion regarding reject or not to reject HO?
