Compute the number of replicates
required for a completely
randomized 3×4 factorial
experiment. Assume we have an
estimate of 25 for O (the residual
standard error), we want a power of
at least 0.8, use a = 0.05, and we
want to be able to detect MAIN
effects for the factor with the 4
levels if the difference between any
two means (of this factor) exceeds
40 units.
