Suppose you conduct a hypothesis test about a population mean when the standard deviation is unknown by calculating at statistic and determining whether to reject the null hypothesis. Assume that your t statistic is a positive value and that you will reject the nul hypothesis when tis very large. For cach of the potential changes to the components of your study design or the results listed below, determine the change t the t statistic, and then select "Increases," "Decreases," or "Stays the same" from the dropdown menu in the right-hand column. Change in Study Design or Results The t statistic A switch from using a two-tailed test to a one-tailed test An increase in the sample variance (s2) A decrease in the significance level (such as using a01 instead of a.05) An increase in the sample size (n)
