Question
![### Earthquakes
A random sample of 42 earthquakes that have occurred between January 2015 and September 2017 was selected, and for each earthquake, the magnitude of the earthquake and the number of people killed were recorded. The data appear in the scatterplot below.
#### Scatterplot Analysis
The scatterplot depicts the relationship between the magnitude of earthquakes (on the x-axis) and the number of people killed (on the y-axis). The magnitude of earthquakes ranges from 0 to 10, and the number of people killed ranges from -150 to 400. Each point on the graph represents an individual earthquake.
Key insights from the scatterplot:
- There is a noticeable trend where higher magnitude earthquakes tend to result in a greater number of fatalities.
- For magnitudes below approximately 6, the number of fatalities is relatively low, often close to zero.
- For magnitudes of 6 and above, there is a significant increase in the number of fatalities, with some earthquakes resulting in over 300 deaths.
#### Question for Consideration
2. Specific to this situation and in words, what is the independent variable?
- [ ] Number of People Killed
- [ ] Magnitude of Earthquake](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff3c0899a-5c62-4a86-a39c-5b160af6a916%2F4efba8bd-9409-441d-8b8b-1772bf53f7e1%2Fr0fsqq4_processed.jpeg&w=3840&q=75)
