E 500

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.

F 500
