In medical? studies, suppose that a true effect exists only 20?% of the time. Suppose also that when an effect truly? exists, there's a 46?% chance of making a Type II error and failing to detect it. Given that H0 is? rejected, approximate the probability of a Type I error by considering a tree diagram of what you would expect to happen with 1000 medical studies that test various hypotheses. Assume a significance level of 0.05. Round your answer to two decimal places.
