Let π denote the proportion of schizophrenics who respond positively to treatment.Atest is conducted ofH0:

π = 0.50 against Ha:π > 0.50, for a sample of size 25, using

α = 0.05.

(a) Find the region of sample proportion values for which H0 is rejected.

(b) Suppose that π = 0.60.

Find P(Type II error).
