The histogram of the distribution plotted on the y - axis and the interval for the length of time on the x - axis is attached below.
<h3>How to denote the histogram?</h3>
The first bar denotes the length of time between 0 and 10 having a frequency of 8. The second bar denoted the interval between 10 and 15 with a frequency of 15
The third bar denoted the interval between 15 and 20 with a frequency of 10. The fourth bar denoted the interval between 20 and 30 with a frequency of 11
