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 material.

Manufacture 1 2 3 18 27 24 27 27 18 21 33 27 21 24 21 a. Compute the values below (to 2 decimals, if necessary).

Sum of Squares, Error 130.5 Mean Squares, Error 14.5 Fisher's LSD Value b. Use Fisher's LSD procedure to develop a 95% confidence interval estimate of the difference between the means for manufacturer 1 and manufacturer 2. Round to two decimal places. Enter negative values as negative numbers. ____ to ____

I am having a hard time finding Fisher's LSD Value. Can someone help me and help me find part B as well?

Thank you very much and can you leave step by step details
