Select the true statement(s). In a hypothesis test concerning a population mean when the population standard deviation o is unknown, the test statistic is based on the standard normal distribution when the sample size is greater than 30. The hypothesis test concerning a population mean when the population standard deviation & is unknown is valid only when the underlying population is normal. In a hypothesis test concerning a population mean when the population standard deviation o is unknown, the p value can never be determined. In a hypothesis test concerning a population mean when the population standard deviation o is unknown with alternative hypothesis H₁ μ> Mo, the value of the test statistic will always be greater than 0. In a hypothesis test concerning a population mean when the population standard deviation o is unknown, the test statistic is based on a t distribution with n 1 degrees of freedom, where n is the sample size. In a hypothesis test concerning a population mean when the population standard deviation o is unknown, there are only three possible alternative hypotheses.
Select the true statement(s). In a hypothesis test concerning a population mean when the population standard deviation o 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 + ß = 1. 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. 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. In a hypothesis test concerning a population mean when the population standard deviation o is known, the conclusion is dependent on whether the value of the test statistic lies in the rejection region. In a hypothesis test concerning a population mean when the population standard deviation o is known, there are only three possible alternative hypotheses. 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.
