Manufacturer N 8 MANKN 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). X Sum of Squares, Treatment Sum of Squares, Error Mean Squares, Treatment x Mean Squares, Error Calculate the value of the test statistic (to 2 decimals). X 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 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). X What conclusion can you draw after c st
