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 | | Q Sum of Squares, Error m * 0 Mean Squares, Treatment v _ 0 Mean Squares, Error _}]T ] 0 k Calculate the value of the test statistic (to 2 decimals). | D 1 } The p-value is| less than 0.01 v @ 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 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). What conclusion can you draw after carrying out this test
