Based on the information provided in your question regarding the energy usage graph, here's how to evaluate the conclusions:
-
More kilowatt-hours were used during cooler months than warmer months.
- This could be true if energy usage spikes during winter months for heating, but without seeing the actual data, it's hard to definitively conclude this.
-
Less kilowatt-hours were used in March than any other month.
- This statement can only be confirmed or denied by checking the energy usage values for March against all other months in the graph. Without the graph, this cannot be concluded.
-
The month of December was the coldest month of the year.
- This cannot be concluded from the energy usage alone unless energy consumption patterns (higher for heating in December if it was colder) are explicitly shown for that month compared to others.
-
The months of July, August, and September were the warmest months.
- This is likely to be true since these months typically have higher cooling energy usage due to the electric air-cooling system. However, again, confirmation depends on the visual data from the graph.
Conclusion
If I were to choose the most reasonable conclusion from the provided statements, I would lean towards “The months of July, August, and September were the warmest months” as it aligns with typical seasonal weather patterns and usage. However, to make a definitive conclusion, viewing the actual graph would be necessary.
