A sample of participants took part in a hearing experiment. Among other things, the absolute hearing threshold (in decibels) was measured for each participant. The measurements were as follows:25, 22, 18, 35, 37, 34, 31, 27, 24, 30, 30, 26, 26, 26, 23, 23, 23, 20, 20Draw the histogram for these data using an initial class boundary of , an ending class boundary of , and classes of equal width. Note that you can add or remove classes from the figure. Label each class with its endpoints.
