Step-by-step explanation:
The given data is presented as follows;
2.21
2.25
2.76
3.1
3.3
3.5
3.6
3.77
3.8
4.23

From the data, we have;
The frequency or number of runners that run between 0 and 1 hour = 0
The frequency or number of runners that run between 1 and 2 hours = 0
The frequency or number of runners that run between 2 and 3 hours = 3
The frequency or number of runners that run between 3 and 4 hours = 6
The frequency or number of runners that run between 4 and 5 hours = 5
With the above frequencies for the different data ranges, the histogram of the given data is then constructed as attached.
