Discussion:
Q1. We have now studied two statistics Z and t. Compare and contrast the use of these two statistical tests, with particular attention to the quantity and quality of the data we use in each test. Is one test better than the other?
Q2. In research the concept of p value is useful to interpret the results of a hypothesis test. Define p value and discuss its relationship to the calculated value of a test statistic such as Z.
If you were reading a professional journal article and saw a p value of0.001 would this support or be inconsistent with the research hypothesis Ha?
