To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturens, the Jacobs Chemical Company obtained the following deta on the time (in minutes) needed to mis the material Manufacturer 24 30 21 30 28 20 28 33 24 26 29 23 a. Use these data te test whether the population mean times for mixing a batch of material difer for the three manufacturers. Use a0.05. Compute the values below (to 2 decimals, necessary). Sum of Squares, Treatment Sum of Squares, Error Mean Squares, Treatment Mean Squares, Eror Calculate the value of the test statistic (to 2 decimals). The pvalue is Selet your answer What is your condusien? Select your anewer b.
