a. Construct a segmented bar graph to display the relationship between age group and response to the question about video games.

b. Describe the association shown in the segmented bar graph in part (a).

Short Answer

Expert verified

Part (a)

Part (b)

Step by step solution

01

Part (a) Step 1: Given information

02

Part (a) Step 2: Calculation

From the above distribution table, we must first generate a table with percentages for each age group. As a result, we must divide counts by the total of their respective columns, then multiply by 100

Following table shows that table:

Using table, the segmented graph will be

03

Part (b) Step 1: Calculation

The segmented graph will be:

The green portion of the bars rises with age, as shown in the graph. As a result, elderly persons are less likely to engage in video game activity.
