Question:

means is at least 0.90? Assume that ( $ 0.05 and that a reasonable estimate of the error variance is !2 $ 25.

3.45. Refer to Problem 3.44.

(a) How would your answer change if a reasonable estimate of the experimental error variance were !2 $ 36?

(b) How would your answer change if a reasonable estimate of the experimental error variance were !2 $ 49?

(c) Can you draw any conclusions about the sensitivity of your answer in this particular situation about how your estimate of 2 affects the decision about sample size?

(d) Can you make any recommendations about how we should use this general approach to choosing n in practice?
