Discussion Post:

1. Create a research question that compares the means of any two populations. Write down the research question. For example, a research question might be whether the mean Graduate Record Exam quantitative score for females is significantly less than the mean Graduate Record Exam quantitative score for males.
2. Create the correct Ho (null hypothesis) and Ha (Alternative or research hypothesis) to represent your research question. Include the Ho and Ha here. Why does the Ho always have an equal sign?
3. Suppose you perform the hypothesis test and determine that your p value is NOT less than your alpha value. Given this, write a full conclusion for your research question (assume alpha is .05).
4. If you incorrectly reject your null hypothesis, what error type would this be and in words what error would you be making in your conclusions?
