To study the effect of temperature on yield in a chemical process, five batches were produced at each of three temperature levels. The results follow. 50C 60C 70C Error Temperature 33 Total 23 Treatments Source of Variation 37 40 32 30 32 35 23 20 22 Construct an analysis of variance table. (Round your values for MSE and F to two decimal places, and your p-value to four decimal places.) Degrees of Freedom Sum of Squares 27 27 30 39 Mean Square F p-value Use a 0.05 level of significance to test whether the temperature level has an effect on the mean yield of the process.
