April is Mathematics Awareness Month and the theme this year is Mathematics, Statistics, and the Data Deluge. There is evidence of data collection, display and analysis all around. You have learned about many types of data displays and will learn many more throughout the years. It is important to be able to look at data and be able to create a display and analyze what you see. The data tells a story.

Create a double line graph comparing the number of female athletes and the number of male athletes participating in the Olympics since the games were last in Los Angeles. (Use the attached graph paper on page 8). 2. Name one Olympic year when more than 1/3 of the athletes were female. Use data from the chart to explain your answer. Show your work 3. Write and answer five questions about the data in the chart. 4. Of the years shown, about what percentage of the Olympic Games had less than 100 countries participating? How did you get your answer? Show your work. Use the data below regarding gold medal times for the 100 meter run for 1936 and 2008 to answer questions 5-8. 1936 2008 GOLD Jesse Owens, USA 10.3 GOLD Usain Bolt, JAM 9.69 SILVER Ralph Metcalfe, USA 10.4 SILVER Richard Thompson, TRI 9.89 BRONZE Martinus Osendarp, HOL 10.5 BRONZE Walter Dix, USA 9.91 5. What is the difference in times for winning a gold medal in 1936 and in 2008? 6. How much time would have to be taken off of the top runners in 1936 in order for them to receive gold, silver and bronze racing against the 2008 winners? Show your work. 7. Which is greater, the difference between the gold medal winner and the bronze medal winner in 1936 or 2008? Explain your answer. 8. Usain Bolt has broken his record since the 2008 Olympics by 11/100 of a second. What is the new time that he ran 100-meters? 9. Three friends are sharing 36 cookies. Jerry states that he wants 25% of the cookies, Gary wants ½ of the cookies and Terry wants 0.75 of the cookies. How many cookies does each person want? Can they each get what they want?
