Q
What are one-tailed tests?
A
These are tests where the alternative hypotheses are in the form of H 1 : P < and H1 : p >
3
Q
What are two-tailed tests?
A
Hypothesis test with an alternative hypothesis in the form of H1 : p ≠
4
Q
What is a critical Region?
A
A CR is a region of the probability distribution which, if the test statistic falls within it, would cause you to reject H0
