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 30 27 24 20 28 29 32 31 29 35 20 31 28 24 32 Construct an analysis of variance table (to 2 decimals but p-value to 4 decimals, if necessary). Source Sum Degrees Mean of Variation of Squares of Freedom Square F p-value Treatments 69 Error 12 Total 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 - Select your answer - X What is your conclusion? -Select your answer - X
