Welcome! • The big idea of Unit 5 •Incorporating SMPs into applications of statistics • Resources Wiki/Email Questions • What is different about S.ID.2 in this course and when it was addressed in Accelerated Coordinate Algebra/Analytic Geometry A? Wiki/Email Questions • What is different about S.ID.2 in this course and when it was addressed in Accelerated Coordinate Algebra/Analytic Geometry A? The difference is using Standard Deviation as a measure of spread as opposed to Absolute Mean Deviation. From a class containing 12 girls and 10 boys, three students are to be selected to serve on a school advisory panel. Which of the following is the best sampling method, among the four, if you want the school panel to represent a fair and representative view of the opinions of your class? Adapted from Illustrative Mathematics S-IC School Advisory Panel 1. Select the first three names on the class roll. 2. Select the first three student who volunteer. 3. Place the names of the 22 students in a hat, mix them thoroughly, and select three names from the mix. 4. Select the first three students who show up for class tomorrow. Adapted from Illustrative Mathematics S-IC School Advisory Panel What’s the big idea? • • • Summarize, represent, and interpret data on a single count or measurement variable Understand and evaluate random processes underlying statistical experiments Make inferences and justify conclusions from sample surveys, experiments, and observational studies. What’s the big idea? Standards for Mathematical Practice What’s the big idea? • SMP 1 – Make sense of problems and persevere in solving them • SMP 2 – Reason abstractly and quantitatively • SMP 3 – Construct viable arguments and critique the reasoning of others • SMP 4 – Model with mathematics • SMP 5 – Use appropriate tools http://blog.mrmeyer.com/ strategically http://bit.ly/17QDmw9 http://www.schooltube.com/video/81f35b2779ef8d4727fd/ http://www.youtube.com/watch?v=jRMVjHjYB6w Coherence and Focus • K-9th Develop understanding of statistical variability Summarize and describe distributions Use random sampling to draw inferences about a population and comparative inferences about two populations Summarize, represent and interpret data on a single count or measurement variable (No standard deviation) • 11th-12th Evaluate outcomes of decisions Examples & Explanations Automobile manufactures have to design the driver’s seat area so that both tall and short adults can sit comfortably, reach all the controls and pedals, and see through the windshield. Suppose a new car is designed so that these conditions are met for people from 58 inches to 76 inches tall. The heights of adult men in the US are approximately normally distributed with a mean of 70 inches and a standard deviation of 3 inches. Heights of adult women are approximately normally distributed with a mean of 64.5 inches and a standard deviation of 2.5 inches. Adapted from Illustrative Mathematics S-ID.4 Do You Fit In This Car?

The heights of adult men in the US are approximately normally distributed with a mean of 70 inches and a standard deviation of 3 inches. What percentage of US men will not be accommodated by the car? For men, we want the percentage of the normal distribution with mean 70 and standard deviation 3 that is above 76 inches or below 58 inches. 76−70 6 =3=2 3 standard deviations above the mean and standard deviations below the mean.

The area is 0.00466, so that about 0.5% of adult women will not fit in this car. Adapted from Illustrative Mathematics S-ID.4 Do You Fit In This Car? Examples & Explanations In 1978, researchers Premack and Woodruff published a study in Science magazine, reporting an experiment where an adult chimpanzee named Sarah was shown videotapes of eight different scenarios of a human being faced with a problem. After being shown each videotape, she was presented with two photographs, one of which depicted a possible solution to the problem. In the experiment, Sarah picked the photograph with the correct solution seven times out of eight.

After being shown each videotape, she was presented with two photographs, one of which depicted a possible solution to the problem. In the experiment, Sarah picked the photograph with the correct solution seven times out of eight. Does the outcome of Premack and Woodruff’s experiment provide evidence that Sarah was recognizing correct solutions, and not just randomly guessing? Explain.

Explain. Using a coin flip simulator you can see that 7 or more successes out of 8 trials rarely happens by pure chance. Adapted from Illustrative Mathematics S-IC Sarah the Chimpanzee Examples & Explanations A bank has placed 1,500 marbles in a very large, clear jar near the customer entrance. Since the bank’s logo’s colors are blue and white, some of the 1,500 marbles are blue and the rest are white. In order to enter the contest, a customer must fill in an entry form with his/her estimate for the percentage of blue marbles in the jar. The entry form says the following: I think that 1 out of every _________ marbles in this jar is blue. (Fill in the blank with a “2”, “3”, “4”, “5”, or “6”.)
