1. Section 5.1

2.  Three ways to answer this question: 1. Actually carry out an experiment 2. Develop a probability model 3. Start with a model, and then use a procedure to simulate repetitions ▪ We’ll use technology

3.  The imitation of chance behavior based on a model that accurately reflects the experiment under consideration

4. 1. State: Ask a question of interest about some chance process. 2. Plan: Describe how to use a chance device to imitate one repetition of the process. Tell what you will record at the end of each repetition. 3. Do: Perform many repetitions of the simulation. 4. Conclude: Use the results of your simulation to answer the question of interest.

5. First: Seed the calculator. TI-83/84 Instructions: Type in a number (I suggest birthday) Press STO> (above ON) Press MATH Go  to PRB Select 1 :rand Press ENTER twice Your calculator is now seeded

6. Press MATH Go  to PRB And down to 5:randInt( Press ENTER Type the number range (Ex. if you have 130 entries, type 1, 130) If you want the calculator to give you more than one entry at a time, type it last (5) Press ENTER If you have a repeat, press ENTER again Select those entries as your sample

7.  The command randInt(0, 9, 5) generates 5 random digits between any two specified values.  The command randInt(1, 6, 7) could be used to simulate rolling a die 7 times.

8. HP Prime Instructions to seed: Press Highlight Statistics 2Var Press Select Math > 5 Probability > 4 Random > 4 Seed Press Type in number (I suggest birthday) Press Your calculator is now seeded

9. Type in range (1, 130) Press however many times to get your sample. Press Select Math > 5 Probability > 4 Random > 2 Integer Press If you have a repeated number, hit again.
