Question

A sample of16 participants took part in a hearing experiment. Among other things, the absolute hearing threshold (in decibels) was measured for each participant. The16

measurements were as follows: 25,22,18,35,37,34,39,39,36,36,36,33,33,30,30,30

Draw thehistogramfor these data using an initial class boundary of17.5, an ending class boundary of42.5, and5classes of equal width.

Note that you can add or remove classes from the figure. Label each class with its endpoints.
