To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical Company obtained following data on the time (in minutes) needed to material. Manufacturer 1 2 3 23 31 17 29 29 16 27 34 20 25 30 19 a. Use these data to test whether the population mean times for mixing a batch of material differ for the three manufacturers. Use a = 0.05. Compute the values below (to 2 decimals, if necessary). Sum of Squares, Treatment 402.67 Sum of Squares, Error 44 Mean Squares, Treatment 201.33 Mean Squares, Error 4.89 Calculate the value of the test statistic (to 2 decimals). 41.18 3
