Question: Create a research question in which you have interest and think of a setting where you could perform a test using a one-sample z -score. (If you are not sure of the population mean for the variable of interest, you may invent a hypothetical population mean for the sake of this Discussion.) For this research question, clearly identify the independent and dependent variables you would study; explain whether a one-tailed or two-tailed test is most appropriate and why; generate a testable null statistical hypothesis and the alternative statistical hypothesis; and select an alpha level of .05, .01, or .001 and justify your choice.
