A researcher plans to conduct a significance test at the a = 0.01 significance level. She designs her study to have a power of 0.90 at a particular alternative value of the parameter of interest. 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 is

(a) 0.01.

(b) 0.10.

(c) 0.89.

(d) 0.90.

(e) 0.99.
