FYI, our mock exam was the 2015 exam and you can find the rubric here. Thing we learned from this test:
- Use the statistical words we have learned to answer questions.
- If asked yes or no, start your answer "yes" or "no". Also remember that increases the sample size by X times decreases the margin of error by sqrt(X).
- Show work! Do NOT round expected value (1.73 ATM's. NOT 2.).
- Use the wording of the question and do not use past-tense to describe a parameter. Checking the independence condition is wrong for an experiment.
- Frequency means counts.
- "Sampling Distribution of Sample Means"--so dang simple man! Just state a center, shape, and spread.
- Don't feel pressure to fill all the provided space.
- Reading the whole problem before you answer the first part is often a great choice.
