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. Temperature 50°C 60°C 70°C 37 31 30 27 32 35 39 35 35 42 24 37 35 28 38 Construct an analysis of variance table (to 2 decimals but p-value to 4 decimals, if necessary). Source of Variation Sum of Squares Degrees of Freedom Mean Square F p-value Treatments 103.33 2 51.67 2.63 0.1132 Error 236 12 19.67 Total 339.33 14 Use a 0.05 level of significance to test whether the temperature level has an effect on the mean yield of the process. Calculate the value of the test statistic (to 2 decimals). The p-value is greater than 0.10 What is your conclusion?
