Question

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 26 22 20 27 27 32 30 27 35 19 29 28 23 30 Construct an analysis of variance table (to decimals but p-value to decimals, if necessary). Source of Variation Sum of Squares Degrees of Freedom Mean Square F p-value Treatments Error Total Use a 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 decimals). The -value is - Select your answer -less than 0.01between 0.01 and 0.025between 0.025 and 0.05between 0.05 and 0.10greater than 0.10Item 12 What is your conclusion? - Select your answer -Conclude that the mean yields for the three temperatures are not all equalDo not reject the assumption that the mean yields for the three temperatures are equalItem 13
