To find the total number of people who participated in the survey, we need to add the frequencies of each time range provided on the graph:

  • 4-6 minutes: 4 people
  • 7-9 minutes: 5 people
  • 10-12 minutes: 2 people
  • 13-15 minutes: 3 people
  • 16-18 minutes: 2 people
  • 19-21 minutes: 1 person
  • 22-24 minutes: 1 person

Now, we can sum these numbers:

4 + 5 + 2 + 3 + 2 + 1 + 1 = 18

So, the total number of people who participated in the survey is 18.

Thus, the correct response is 18.
