1. Comparing the t and the zstatislics You can use both the t-statistic and the 2-statistio to test hypotheses about the mean of a population. The test that uses the t-statistio is typically referred to as a t-test, while the test that uses the z-statistio is commonly called a z-test. Which of the following statements are true of the t statistic and the t distribution? Check all that apply. l. The t distribution is the same for anyI sample size. l_. The numerator of the t statistic is different than the numerator ofthe 2 statistic. IWhen you do not know the population standard deviation, you can use the t statisticJ assuming all relevant assumptions are satisfied. l. The formula for the t statistic is t = {)2 - u) I sfy'n
