# Need help with a statistics question to examine assumptions and limitations

**Question description**

In this discussion, you will

evaluate a research question and determine how that question might best be

analyzed. To do this, you will need to identify the appropriate

application of course specified statistical tests, examine assumptions and

limitations of course specified statistical tests, and communicate in writing

critiques of statistical tests.

A researcher wishes to study the

effect of a new drug on blood pressure. Consider and discuss the

following questions as you respond:

Would you recommend using a z-test, a t-test, or an

ANOVA for the analysis? Explain your answer.

- What would your choice of test depend on? For the

test you select, explain your design and your comparison groups. - Would the hypothesis be directional or

non-directional? - Would the test be one-tailed or two-tailed?
- What would be the null and what would be the

alternative hypothesis?
