Question

Create a scatterplot for the data in the table. based on the appearance of the scatterplot, which model does the data appear to follow?

a. the data appears to follow a linear model
b. the data appears to follow a quadratic model
c. the data appears to follow a cubic model
d. the data appears to follow an exponential model

Answer 1

C. The data appear to follow a cubic model.

Explanation:

Plot the points on the graphing calculator, and then generate the best regression model.

For the linear equation, r = -.0529

For the quadratic equation, R^2 = .8992

For the cubic equation, R^2 = .9678

For the exponential equation, r = -.0814

A cubic regression equation would best fit this data. So the correct answer is C.
