Chapter 11: Q. 27 (page 753)

The color of candy Inspired by the example about how background music influences
choice of entrée at a restaurant, a statistics student decided to investigate other ways to
influence a person’s behavior. Using $60$ volunteers, she randomly assigned $20$ volunteers
to get a “red” survey, $20$ volunteers to get a “blue” survey, and $20$ volunteers to get a
control survey. The first three questions on each survey were the same, but the fourth and
fifth questions were different. For example, the fourth question on the “red” survey was
“When you think of the color red, what do you think about?” On the blue survey, the
question replaced red with blue. On the control survey, the last two questions were not
about color. As a reward, each volunteer was allowed to choose a chocolate candy in a red
wrapper or a chocolate candy in a blue wrapper. Here are segmented bar graphs showing
the results of the experiment. Describe what you see.

Short Answer

Expert verified

The more chosen chocolate color was the same as the survey's color. In the control survey, blue chocolates were chosen more often.

Step by step solution

Given Information

We have been given a graph which gives the percentage of blue and red colored chocolates chosen in the red survey, blue survey, and control survey.

Explanation

The blue candy was chosen by more than $60 %$ of those who participated in the blue survey. The red candy was chosen by $60 %$ of those polled in the red survey. When compared to those in the red survey, individuals in the control survey were more inclined to choose the blue treat. When compared to those who took the blue survey, a larger percentage of those who took the red survey picked the red candy.
