Mykel surveyed 15 7th graders and 15 8th graders at his school to see how many hours they spend per day listening to music. He made two box plots to compare the data sets. What inference can he draw from the data sets?
The range is greater for the 8th graders, so there is greater variability for the 8th graders than the 7th graders.
The person who listens to music the least is a 7th grader.
The median is greater for the 7th graders, so they generally spend more time listening to music than 8th graders.
