Leonard Rowland · Answer 1

481 / 2142 = 22.46%

A pie chart is also commonly used to illustrate it.

Step-by-step explanation:

We can get the sample proportion of every case, applying the following relations:

1288 / 2142 (60.13%) answered "no"

481 / 2142 (22.46%) answered "yes"

373 / 2142 (17.41%) had no opinion

where 2142 (1288 + 481 + 373 = 2142) is the total of adults who were asked.
