A sample of 19 participants took part in a hearing experiment. Among other things, the absolute hearing threshold (in decibels) was measured for each participant. The 19 measurements were as follows: 25, 22, 18, 35, 37, 34, 31, 27, 24, 30, 30, 26, 26, 26, 23, 23, 20, 20, 17 Draw the histogram for these data using an initial class boundary of 16.5 and a class width of 5. Note that you can add or remove classes from the figure. Label each class with its endpoints. Frequency X 5 ? + + 0 0 0 0 Absolute hearing threshold (in decibels) E
