Final Exam Study Guide: Part 2

1. Understand the difference between mean, median, and mode. Be able to create a sample that has the given values.
2. Label a bell curve to demonstrate the 68-95-99.7 rule.
3. Find the probability of several events happening. Look at problems like "all three", "none of the three", and "at least one of the three".
4. You are given a joint frequency table (contingency table). Use it to find some probabilities. These probabilities could be joint (event A and event B at the same time), marginal (only one event is mentioned), union (event A or event B [or both]), or conditional (given one event has already happened, find the probability of another). Leave your answer as fractions. Conduct a test for independence from the contingency table.
5. Find some bayesian probabilities. This is where you're given the probabilities in one order and then asked for a conditional probability in another order. Similar to the dish washing problem at the end of chapter 15 problems.
6. Identify whether or not the situation is a binomial experiment. If not, explain why not.
7. A probability distribution is given. Find the mean and standard deviation. The table with xp(x) and x2p(x) is given for you to complete, but you'll need to know what to do with the values after finding them.
8. Construct a box plot from the five number summary. Conduct a two sample t test.
9. Conduct a proportion test.
10. Conduct a test for correlation. Be able to write the regression equation from the table of coefficients. Be able to find the missing values in the table of coefficients. Estimate the response variable for the given value of the predictor variable. Be able to find the coefficient of determination when you're given the correlation coefficient.
11. Write the hypotheses for a one-way ANOVA test, complete the ANOVA table given the SS column and information about the data. Give the decision and conclusion for a one-way ANOVA test.
12. Write the concept that is fundamental to all hypothesis testing.
13. Identify which statement is the null hypothesis and which is the alternative hypothesis.
14. Identify which statement is a type I error and which is a type II error.
15. Given critical value(s) and a test statistic, identify the test as left tailed, right tailed, or two tailed and give the conclusion.
16. Given a p-value and significance level, write the decision.
17. For each claim, write the null and alternative hypotheses and identify the test as left tailed, right tailed, or two tailed.

Notes

• This is the second part of your final exam. For the most part, questions are similar to questions from your old tests. There are a few exceptions.
• Go through your old tests and correct the problems you missed (or at least those that are like questions on the final).
• This exam is open notebook. This may include your old tests, activities, technology projects, etc. I would certainly put this study guide in the front of your notebook. You may wish to go through and organize your notes or tests according to this study guide. Put stick-it-notes or otherwise mark the sections you will need during the exam.
• You may not use your textbook. The normal, t, and chi-square tables will be provided for you during the exam.
• The computers will be off during the exam. You do not need Minitab.
