If the probability that you will correctly reject a false nu

If the probability that you will correctly reject a false null hypothesis is 0.80 at 0.05 significance level. Therefore, is__ and is__.

a. 0.05, 0.80

b. 0.05, 0.20

c. 0.95, 0.20

d. 0.95, 0.80

Solution

alpha = 0.05 (significance level)

beta = 1 - power = 1- P(correctly rejecting false null) = 1 - 0.80 = 0.2

option (b)
