Based on the sales trend line, how many bottles of domestic nonsparkling water will be sold in the U.S. in the year 2008? About 8,900 Million Gallons 4. This time use the equation of the LinReg line to predict how many bottles of domestic non-sparkling water will be sold in the U.S. in the year 2008. N(9) = 8,928 Million Gallons also find Gallons ©2010 Beyond Benign – All Rights Reserved. N(13) = 11,234 Million 5. What does N(13) represent? N(13) represents the projected numberof gallons of bottled water consumed in the U.S U.S. Bottled Water Consumption 2000 to 2007 a.) Domestic, b.) Sparkling and c.) Imports 2000 = year 1 2001 = year 2 etc. Key Domestic Sparkling water Imports Number gallons of bottled water consumed in the U.S. ( x 1 million) 6. On the same graph make a connected line graph of the sales volume data for: Time : Year 7. Describe the trends over time for domestic sparkling bottled water and imported bottled water consumption in the U.S. for the years 2000 to 2007. Both are trending upward over time. Sparkling sales are more steadily increasing. Imports are up and down. 8. Based on the sales trends, predict the number bottles of Domestic Sparkling Bottled Water and Imported Bottled Water that will be consumed in the U.S. in the year 2008? From my graph I predict that sparkling bottled water sales will be 205 million gallons in 2008 and that imports will increase to 225 million gallons. 9. In which prediction are you the most confident? Why? ©2010 Beyond Benign – All Rights Reserved. I am most confident in the domestic sparkling trend prediction. The trend is steady but erratic for imports. 10. Use a graphing calculator to find a regression line (LinReg) for each data set. Domestic Sparkling Bottled Water: S(x) = 8.88x + 126.6 Pearson Correlation Coefficient: Imported Bottled Water: r = 0.966 I(x) = 7.68x + 137.3 Pearson Correlation Coefficient: 11. Find: r = 0.5683 S(9) = 206.52 I(9) = 206.42 S(9) = 8.88 • (9) + 126.6 I(9) = 7.68(9) + 137.3 12. What do the values S(9) and I(9) represent? S(9) Represents predicted sales of Domestic sparkling water in 2008 I(9) Represents predicted sales of Imported bottled water in 2008 13. Which prediction is more reliable? Why? I have far more confidence in the projections in 2008 for domestic sparkling water because the sales trend has been steady over time. ©2010 Beyond Benign – All Rights Reserved.

Objectives: Students will… Consider bottled water and its impact on the environment. Analyze global water markets using pie charts Procedure: Show the Water-Disaster video. Lead a discussion with the students about bottled water, if they drink it and why. Explain to students that they are going to work with some numbers that really show the impact of bottled water consumption in the world. Hand out the student sheet.

The Global Bottled Water Market A Statistical Analysis of Data Name: ____________________________ Hour:_____ The consumption of bottled water has been increasing across the globe. The increase in bottled water production also leads to the increase in empty plastic water bottle waste. These plastic bottles are sometimes recycled but more often end up in landfills or as litter. In this problem you will compare and contrast per capita bottled water consumption data for the top twenty countries in the years 2002 and 2007. Using a graphing calculator; 1. Find the mean and median for each data set. 2002: mean: _________ median: _________ 2007: mean: _________ median: _________ 2. Find the standard deviation for both sets. 2002: ____________ 2007: _____________ ©2010 Beyond Benign – All Rights Reserved. 3. Make a box and whisker plot for 2002 and 2007.
