# Exam 1 Study Guide: Chapters 1-3

1. Use the bar chart to answer the questions. Four parts.
2. You are given a raw score, the mean, and standard deviation. Find the standardized score. Look at problems 2.6.5-8.
3. You are given a standardized score, the mean, and standard deviation. Find the raw score. Look at problem 2.6.38
4. Use the pie chart to answer the questions. Four parts.
5. Create a probability distribution from a description and then answer questions based on it. The description will be something like "A six sided die is rolled. The odd numbers are twice as likely to occur as the even numbers."
6. A simulation is conducted to determine the chance of something occurring. Use the results of the simulation to find the probabilities.
7. A simulation is conducted to determine the average time before something happens. Use the results of the simulation to find the average.
8. Given a small set of data values, find the mean, median, mode, midrange, variation, variance, and standard deviation. Look at problems 2.4.1-8, 2.5.1-8.
9. Read and interpret an ogive.
10. Identify the type of sampling used. Ten parts. Look at problems 1.4.9-20.
11. Look at a histogram where the bars are one standard deviation wide. Determine the percent of the data that lies within one, two, and three standard deviations of the mean and whether or not 68-95-99.7 rule applies. Chebyshev's Rule is stated, see if your data follows that rule.
12. Determine whether or not the graph or chart is appropriate for the type of data described. For example, is a pie chart appropriate when more than one category can be selected? Is a histogram appropriate for two related numerical variables. Six parts.
13. Use a joint probability distribution in table form to find some probabilities. Six parts. Leave answers in fraction form.
14. Find the probabilities of some simple events. Look at activity 1.
15. Find the probabilities of some compound events using the multiplication rules. Look at activity 1.
16. Create a tree diagram that illustrates the described situation. Use the tree diagram to complete a table of joint probabilities. Then use the table to answer some probability questions. Look at activity 1.

## Notes

• You will need a calculator.
• You will not need Minitab or Statdisk. Your computer screens should be off during the exam.
