Power For a hypothesis test with a specified significance level α, the probability of a type I error is α, whereas the probability β of a type II error depends on the particular value of p that is used as an alternative to the null hypothesis.
a. Using an alternative hypothesis of p < 0.4, using a
b. Find the value of β, the probability of making a type II error.
c. Given the conditions cited in part (a), find the power of the test. What does the power tell us about the effectiveness of the test?
