The level of significance only tells us the probability of committing a Type I error (rejecting the null hypothesis when it is actually true). The probability of committing a Type II error depends on other factors such as the effect size, sample size, and power of the test. Therefore, we cannot determine the probability of a Type II error based on the level of significance alone.
