A researcher plans to conduct a test of hypotheses at the α= 0.05 significance level. She designs her study to have a power of 0.80 at a particular alternative value for the parameter of interest. What is the probability that the researcher will commit a Type II error for the particular alternative value of the parameter at which she computed the power?

A) 0.05
B) 0.20
C) 0.80
D) Equal to 1 - (P-value) and cannot be determined until the data have been collected
