11. An experiment is required to resolve a 6 = 12 unit bias between two treatment groups with 90% power. The process noise is normal with standard deviation σ = 12. a. Determine the total number of observations required for the experiment if there is one variable with two levels and the data are to be analyzed by the two-sample t test. b. Determine the total number of observations required if the experiment design is a 24 full factoral design.
