Given: Ho:p≥.8, Ha: p<.8, n=19, Reject Ho if X≤12

(a) Find the level of significance α.

(b) Find β(p1) if in fact p = .5.

(c) Find the power against the alternative p = .5.

(d) Suppose that X is observed to be xo=14

(i) What is your decision?

(ii) What type of error are you subject to?

(iii) Find the P-value.

(e) Set up a rejection region so that α is as close as possible to, but does not exceed .01. State both the 'nominal' α and the 'exact' a.
