Question
The students in a first-grade class were all asked to time how long (in seconds) they could hold their breath. The results were tallied and are presented in the following histogram.
How many of those students held their breath greater than 12.5 but less than 15.5 seconds?
A histogram has a horizontal axis labeled Values from 7.5 to 15.5 in increments of 1 and a vertical axis labeled Frequency from 0 to 6 in increments of 1. The histogram has vertical bars of width 1, starting at the horizontal axis value of 7.5. The approximate heights of the bars are as follows, where the horizontal axis label is listed first and the approximate height is listed second: 7.5, 2; 8.5, 1; 9.5, 4; 10.5, 2; 11.5, 5; 12.5, 2; 13.5, 5; 14.5, 6.
