Select the true statement(s}. D In general. you reject the null hypothesis in a test concerning a population mean when the population standard deviation 0' is known and the value of the test statistic is large in magnitude. I] In a hypothesis test concerning a population mean when the population standard deviation 0' is known. the probability of a type I error a and the probability of a type II error ,6 always sum to 1. That is. a + ,3 : l. I] In a hypothesis test concerning a population mean when the population standard deviation 0' 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 0- is known, there are only three possible alternative hypotheses. U The hypothesis test concerning a population mean when the population standard deviation 0' is known can be used only when the underlying population is normal. In a hypothesis test concerning a population mean when the population standard deviation 0' is known, the conclusion is dependent on whether the value of the test statistic lies in the rejection region
