Question description

Week 3 -
Discussion 1 – Choose the Analysis





A researcher wishes to study the
effect of a new drug on blood pressure.  Would you recommend using a
z-test, a t-test, or an A.N.O.V.A. 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?
