Marrone C S CIMB ULE ULTET, UTENOS CHICO obtained the following data on the time in minutes) needed to mix the material. Manufacturer 1 2 32 22 20 25 16 22 30 21 35 18 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), 31 24 Sum of Squares, Treatment II Sum of Squares, Error Mean Squares, Treatment Mean Squares, Error Calculate the value of the test statistic (to 2 decimals), The p-value is Select your answer What is your conclusion? Do not reject the assumption that mean time needed to mix a batch of material is the same for all manufacturers : b. At the a=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)
