Question

check all the correct options and for the last blank the options are quite different or essentially the same.

You can use both the t statistic and the z statistic to test hypotheses about the mean of population. The test that uses the t statistic is typically referred to as at test, while the test that uses z statistic is commonly called a z test. Which of the following statements are true of the t statistic? Check all that apply. O The formula for the t statistic is t = (M - H) / oM - O The t statistic provides an excellent estimate of z, particularly with small sample sizes. O The t statistic uses the same formula as the z statistic except that the t statistic uses the estimated standard error in the denominator. D The t statistic does not require any knowledge of the population standard deviation. With the exception of whether the population standard deviation is known, the necessary assumptions for hypothesis tests with the t statistic and with the z statistic are
