Question

A number generator was used to simulate the percentage of students in a town who enjoy playing video games. The process simulates randomly selecting 100 students from the town and was repeated 20 times. The percentage of students who play video games is shown in the dot plot. Which statement is true about the student population of the town?

Answer 1

Most likely, 60% to 75% of the students in the town play video games.

Explanation:

Of the 20 samples taken, ...

• 1 is in the range 40%–50%
• 4 are in the range 50%–60%
• 18 are in the range 60%–75%
• 1 is in the range 80%–90%

Most of the samples fall in the range 60%–75%, so we have to conclude that it is most likely that the fraction of students who play video games is in that range.
