In a hypothesis test the probability of a Type II error for a given alternative parameter value is known to be 0.45. Assuming this alternative value is correct, what is the probability of correctly rejecting the null hypothesis (the power of the test)? power = 0.45 power = 0.55 power = 1 More information is needed to answer the question.
