the pull down bar answer options are the same for all the questions except the sentence one

Suppose you conduct a hypothesis test about a population mean when the standard deviation is known (a \"2 test\") by calculating a 2 statistic and determining whether to reject the null hypothesis. Assume that your 2 statistic is a positive value and that you will reject the null hypothesis when 2 is very large. Listed below are possible changes to the study design or to the results of the study. Determine whether the 2 statistic increases, decreases, or stays the same for each of these changes. Use the dropdown menus in the right-hand column to indicate your choice. Change in Study Design or Results The 2 statistic A decrease in the population variance (02) Increases Stays the same Decreases A decrease in the obtained difference (M p) A decrease in the sample size (n) A decrease in the significance level (such as using or = .01 instead of or = .05) Suppose you reject the null hypothesis. Then, the results of your study are
