Question

A survey was taken on the number of songs people have on their music players. The histograms below display the survey results by age group teenagers and adults. (a) what is wrong with the following statement? There are more teenagers than adults that have at least 700 songs on their music player. (b) Change the sentence so that it is an accurate statement.

Answer 1

The number 700 gets into the segment [600,799] and it is not fully correct to say that there are more teenagers than adults that have at least 700 songs. More correctly is to say:
"There are more teenagers than adults that have at least 600 songs" (if you want to estimate amounts of teenagers and adults who have 700 songs).
