Company obtained the following data on the time (in minutes) needed to mix the material. Manufacturer 1 3 2 34 23 22 29 32 21 32 25 27 25 33 24 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, i necessary) Sum or 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 ma 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
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). 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 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? Cannot conclude there is a difference in the mean time for these manufacturers
To tost whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical To tost whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers
