Select the true statement(s). In a hypothesis test concerning a population mean when the population standard deviation & is known, the probability of a type I error a and the probability of a type II error ß always sum to 1. That is, a + B = 1. In a hypothesis test concerning a population mean when the population standard deviation o is known, there are only three possible alternative hypotheses. In general, you reject the null hypothesis in a test concerning a population mean when the population standard deviation o is known and the value of the test statistic is large in magnitude. ✓ In a hypothesis test concerning a population mean when the population standard deviation o is known, the probability of a type II error does not depend on the true value of the population mean. In a hypothesis test concerning a population mean when the population standard deviation & is known, the conclusion is dependent on whether the value of the test statistic lies in the rejection region. ✓ The hypothesis test concerning a population mean when the population standard deviation o is known can be used only when the underlying population is normal.
