A sample of 18 participants took part in a hearing experiment. Among other things, the absolute hearing threshold (in decibels) was measured for each participant. The 18 measurements were as follows: 25, 22, 18, 35, 37, 34, 31, 27, 24, 21, 18, 39, 26, 26, 26, 23, 23, 20 Send data to calculator Draw the frequency polygon for these data using an initial class boundary of 17.5 and a class width of 5. Note that you can add or remove classes from the figure. Label each class with its midpoint.
