Discuss the below:
A: Which of these measurement scales (nominal, ordinal, interval and ratio) can be handled through hypothesis testing?
B: What are the five steps in hypothesis testing? Is the order important? Why or why not?
C: Just what do we mean by "test statistic"?
D: Why do null and alternative hypotheses have to be mutually exclusive?
E: A z-score table shows probability values for a portion of the normal. How would you arrive at a probability value (given in the z-score table) to reflect a two-tailed hypothesis? How would you arrive at a probability value to reflect a one-tailed hypothesis?
