Consider Exercise 4-21, and suppose that the sample size is increased to n  16.

(a) Where would the boundary of the critical region be placed if the type I error probability is 0.05?

(b) Using n  16 and the critical region found in part (a), find the type II error probability if the true mean foam height is 195 mm.

(c) Compare the value of obtained in part

(b) with the value from Exercise 4-21 (b). What conclusions can you draw?

Which has higher power?
