The value which helps you determine how well a model
fits data
F 100
r2
F 100
The table shows the price per capita consumption C (in pounds) of broccoli in the
US. Create a scatter plot.
F 200
Year Consumption
1999 6.2
2000 5.9
2001 5.4
2002 5.3
2003 5.7
What is t
F 200
A cubic model for the broccoli problem is C = 0.0583t3 – 1.796t2 + 17.99t –
52.7
Graph this with the scatter plot. Is it a good fit? Explain.
F 300
What are ?
F 300
Give the quadratic model for the broccoli problem. Is it a
good fit?
F 400
y = .129x2 – 2.99x + 22.76
No; r2 = .903 and it doesn’t fit the graph well
F 400
Use the better model to predict the broccoli
consumption in 2010.
