Chapter 11.1, Problem 23E

a)

To determine

To construct a segment graph.

Explanation of Solution

Given:

Calculation:

From given distribution table, first we need to create a table in which there will be percentage for each age group. Therefore, we need to divide counts by their respective column total and then multiply by 100.

Following table shows that table:

	18-29	30-49	50-64	65+
Yes	67.40%	58.26%	39.76%	24.93%
No	32.60%	41.74%	60.24%	75.07%

Using table, the segmented graph will be:

b)

To determine

To explain association using segmented graph.

Explanation of Solution

Given:

The segmented graph will be:

Calculation:

The graph shows, the green part of the bars increases with increasing age. That means older people are less likely they are to play video games.
