Which of the following statements are true of the t statistic? Check all that apply. The formula for the t statistic is t = (M – µ) / SM The t statistic provides an increasingly bad estimate of z at increasingly large sample sizes. When you do not know the population standard deviation, you can use the t statistic, assuming all relevant assumptions are satisfied. The numerator of the t statistic is different than the numerator of the z statistic. 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
