- What type of graph have the students constructed?
- Why is the teacher asking the students to show the best-fit line?
- Although we only see a short section of the “interpreting the results” part of the lesson,what is the value of the discussion and sharing thoughts about best-fit linepattern?

Exercise 21.1: Simulations

Read the scenario and apply your understandings about using simulations to answer the questions.

The fifth-grade teacher wanted to set up a simulation to have her students test what the probability would be of getting 7 out of 10 questions correct if you guessed on atrue-or-false test.

- What would the purpose be for using a simulation over an experimental probability task?
- The first step in using a simulation is to identify the key component and assumption of the problem. Identify and explain what they are for this scenario.
- The next step is selecting a random device for the key component. What would you recommend that they use for this activity?
- An important part of a simulation is determining and defining what constitutes “onetrial.” The authors recommend 10 times as one trial. Why is that appropriate for thissimulation?
