- Identify the type of sampling used. Six parts. Look at problems 1.4.9-20 and the chapter 1 homework.
- 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? Five parts.
- A graph is given. Use it to answer the questions.
- Complete the data set so that it satisfies the given characteristics. You'll need to know the definitions of mean, median, and mode to do this. For example, if the mean is 20 and the first three numbers are 10, 12, and 45, what is the fourth number? Three parts.
- A mean and standard deviation are given. Label a bell curve to demonstrate the 68-95-99.7 rule.
- 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. Look at questions 3 and 4 on classroom activity 1.
- The mean, median, range, standard deviation, and variance for a dataset are given. Determine what those statistics will be after the indicated transformation is applied. Four parts. Look at the chapter 2 homework.
- 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, the chapter 2 homework, and classroom activity 2.
- Find the probabilities of some simple events. Four parts. Look at the chapter 3 homework.
- Find the probabilities of some compound events using the multiplication rules. Four parts. Look at the chapter 3 homework.
- Be able to take a statistical formula and plug the values into it to evaluate it. In addition, you should know the formula for finding the mean.
- Create a probability distribution from a description. 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."
- Use a joint frequency distribution (contingency table) to find some probabilities. Six parts. Look at the chapter 3 homework.
- 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.
- Simulation problem. Data that can be used to perform a simulation is provided. Use the data to answer the questions.
- Simulation problem. Data that can be used to perform a simulation is provided. Use the data to answer the questions.

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