Question

The histogram to the right represents the weights (in pounds) of members of a certain high-school programming team.What is the class width? What are the approximate lower and upper class limits of the first class?

Answer 1

Looking at the given histogram

we have that

120-110=10

130-120=10

140-130=10

150-140=10

160-150=10

170-160=10

180-170=10

therefore

The class width is 10 lbs

First-class is 110-120 lbs

lower-class limit=110

upper class limit=120
