your research question, the independent and dependent variables

This answer was rated:

★★★★★

your research question, the independent and dependent variables you would study, an explanation of whether a one- or two-tail test is most appropriate, your testable null and alternative hypothesis, and an explanation of which alpha level you would select and a justification of you choice.

Is this there any particular guideline around the type of research question it should be? Any particular subject, domain, or type of hypothesis test? Do you actually need to carry out the research?

Create a research question you are interested in for which the appropriate test of the statistical hypothesis would require the use of a 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.

Determine whether a one-tail or two-tail test is most appropriate and explain why.

Generate a testable null statistical hypothesis and an alternative statistical hypothesis.

Select an alpha level of .05, .01, or .001 and justify your choice.

With these thoughts in mind:

your research question, the independent and dependent variables you would study, an explanation of whether a one- or two-tail test is most appropriate, your testable null and alternative hypothesis, and an explanation of which alpha level you would select and a justification of you choice.
