Create an equation for which the appropriate test of the statistical hypothesis would require the use of a z-score. (For the population mean for the variable of interest, you may invent a hypothetical population mean for the sake of this equation.)
o Clearly identify the independent and dependent variables you would analyze.
o Determine whether a one-tail or two-tail test is most appropriate and explain why.
o Generate a testable null statistical hypothesis and an alternative statistical hypothesis.
o Select an alpha level of .05, .01, or .001 and justify your choice.
