Application Exercises
The bar graph shows the differences among age groups on the
Implicit Association Test that measures levels of racial prejudice.
Higher scores indicate stronger bias. Exercises 91-92 are based
on the information in the graph. In these exercises, the possible
values of the variable x are the group numbers shown in the voice
balloons below the bars in the graph.

91. a. The data can be described by the following polynomial
model of degree 3:
+ (0.1x³ - 1.3x² + 3.3x + 5).
In this polynomial model, S represents the score on the
Implicit Association Test for age group x. Simplify the
model.
b. Use the simplified form of the model from part (a) to find
the score on the Implicit Association Test for the group in
the 45-54 age range. How well does the model describe the
score displayed by the bar graph?
