material 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 the following data on the time in minutes) needed to mix the Manufacturer 1 2 3 16 33 15 22 31 14 20 36 18 18 32 17 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, I Sum of Squares, Treatment Sum of Squares, Error Mean Squares, Treatment Mean Squares, Error Calculate the value of the test statistic (to 2 decimals). The p-value is less than 0.01 What is your conclusion? Conclude the mean time needed to mix a batch of material is not the same for all manufacturers b. At the Q == 0.05 level of significance, use Fisher's LSD procedure to test for the equality of the means for manufacturers 1 and 3. Calculate Fisher's LSD Value (to 2 decimals). What conclusion can you draw after carrying out this test? Cannot conclude there is a difference in the mean time for these manufacturers v Activate Woode
