ANSWER:
Solution:
Step 1 of 3:
The data about the number of earthquakes worldwide in 2010 is given.
We have to find the following.
- The cumulative frequency distribution.
- The cumulative relative frequency distribution.
- The frequency polygon of the data.
- The frequency ogive of the data.
- The relative frequency ogive of the data.
