If X ~N(u, o') and X,, X,,..., x, are observations of ), then the sampling distribution of X - H is a where x is the sample average, and s is the s/ Vn sample standard deviation. Tukey's test is a multiple comparison method that controls the experiment-wise significance level forWrite out the statistical model that was assumed for a single fixed-factor experiment. Define the terms in the model and any model term constraints. What assumption leads to the F distribution as the distribution of MSTreatments/ MSE
