Hi Trina, welcome to MHB!

Did you try anything? Where are you stuck?
Ah well, I'll just throw something out there to see what we can do.

The lowest value is 0 and the highest value is 49.
We can divide them into the classes 0-9, 10-19, 20-29, 30-39, and 40-49.
How many people spent between 0 and 9 minutes reading a political blog?
