Difference Between the Null and Alternative Hypothesis Questions Discussion Use ONLY words (no formulas, no equations, and no symbols): What does a hypothesis test do? How do you determine what is the null hypothesis and what is the alternative hypothesis? What are the primary types of hypotheses tests? For what is each used/What determines which one to use in a particular situation? What type of test statistic is used for each? (You may put the answers for this into a table). What is a p-value? What is critical-value? What does the confidence interval tell you?
