Question: Refer to Exercise 13. a. Compute the quantity s =MSE, the estimate of the error standard deviation . b. Assuming s to be the error

Refer to Exercise 13.
a. Compute the quantity s =√MSE, the estimate of the error standard deviation σ.
b. Assuming s to be the error standard deviation, find the sample size necessary in each treatment to provide a power of 0.90 to detect a maximum difference of 2 in the treatment means at the 5% level.
c. Using a more conservative estimate of 1.5s as the error standard deviation, find the sample size necessary in each treatment to provide a power of 0.90 to detect a maximum difference of 2 in the treatment means at the 5% level?
