Question: Suppose H 0 : p = 0.75 is to be tested against H 1 : p < 0.75 using a random sample of size n

Suppose H0: p = 0.75 is to be tested against H1: p < 0.75 using a random sample of size n =7 and the decision rule "Reject H0 if k ≤ 3."

(a) What is the test's level of significance?

(b) Graph the probability that H0 will be rejected as a function of p.
