Below is the total water consumption in gallons per bird per week for turkeys.

Week Water Consumption per bird (gal/week)

1 0.080

2 0.198

3 0.261

4 0.410

5 0.598

6 0.755

7 0.804

8 1.037

9 1.208

10 1.571

11 1.655

12 1.710

13 1.692

18 1.811

19 1.573

1. Graph the data in a scatterplot with Week on the x-axis and Water Consumption on the y-axis.

2. Give an approximate linear equation to fit the data and indicate the r2.

3. Discuss the fit of the linear equation to the data. Include in your discussion where the line appears to “fit” and where it appears to be the “wrong fit”.

4. Give an approximate equation using a 2nd order to fit the data and indicate the r2.

5. Discuss the fit of the 2nd order polynomial to the data. Include in your discussion where the graph appears to “fit” and where it appears to be the “wrong fit”.

6. Give an approximate equation using a 3rd order to fit the data and indicate the r2.

7. Discuss the fit of the 3rd order polynomial to the data. Include in your discussion where the graph appears to “fit” and where it appears to be the “wrong fit”.

8. Use the internet or another reference to find the definition of r-squared (r2) as it pertains to fitting lines.

9. Based on what you learn about r2, which equation above gives the best fit?

10. Use the best fit equation to predict what water consumption would be at 20 weeks.
