The modification (Mod) sample means are: Mod A = 31.4, Mod B = 28.6, Mod C = 23.8
Using the Fisher LSD test, determine if any of the modifications were significantly different from each other at a level of significance of a = 0.05, and find the upper and lower confidence limits for the difference of means.
