1. Highlighting Standards for Mathematical Practice in an Intro Stats Course by Fides Ushe Springfield College, MA

2. Standard for Mathematical Practice: MP5: Use appropriate tools strategically

3. Common Core Content Standard: CCSS.Math.Content.HSS-IC.B.4 CCSS.Math.Content.HSS-IC.B.4 Use data from a sample survey to estimate a population mean or proportion; develop a margin of error through the use of simulation models for random sampling.

4. IDENTIFY THE POPULATION PARAMETER TO BE ESTIMATED

5. POPULATION PROPORTION p -KEYWORDS- Proportion of all Percentage of all Probability of success p

6. CHECK THE REQUIREMENTS Do you have a simple random sample (SRS)? Are the conditions for a Binomial Distribution met? Is the number of successes, x, in the sample large enough? Is the number of failures, (n-x), in the sample large enough?

7. WHAT DO YOU NEED TO CONSTRUCT A CONFIDENCE INTERVAL for p? x, the number of successes in the sample n, the sample size or the total number of trials in a binomial experiment Level of confidence: c-level - (in decimal form)

8. SELECT APPROPRIATE TECHNOLOGY GRAPHING CALCULATOR-TI-83/84 PLUS

9. SELECT THE CORRECT COMMANDS FOR POPULATION PROPORTION STAT > TESTS > 1-PropZINT x: n: C-Level: Calculate

10. INTERPRET THE CONFIDENCE INTERVAL IN CONTEXT Have you used the correct format for interpreting the confidence interval? Have you included the stated confidence level in your statement?
