The bar chart above displays the survivability percentage of a specific plant species in four seasons—Spring, Summer, Fall, and Winter—across five locations: Denver, Miami, Chicago, Seattle, and Houston. Survivability is defined as the percentage of the plants that survive the season in each location.
From each drop-down menu, select the option that creates the most accurate statement based on the information provided.
The plant species has the lowest average survivability across all locations in season.
On average, across all four seasons, the plant species has the lowest survivability percentage in location.

Official Solution:
Drop-down 1:
• We can visually estimate without calculating exactly. Winter shows the lowest survivability percentages in every city except Miami, where it is the second lowest after Fall. However, when averaged across all locations, Winter would still clearly have the lowest overall survivability
Drop-down 2:
• Denver has the lowest survivability percentage in every season except Spring, where it is the second lowest after Chicago—but not by much. Even without exact calculation, it’s clear that Denver would still have the lowest average survivability among the five locations.
Correct answer:
Dropdown 1: "Winter"
Dropdown 2: "Denver"

1. Let's calculate the average survivability during each season:
- Spring. \(\frac{85\% + 90\% + 80\% + 95\% + 87.5\%}{5} = 87.5\%\).
- Summer. \(\frac{65\% + 95\% + 70\% + 85\% + 91.5\%}{5} = 81.3\%\).
- Fall. \(\frac{70\% + 80\% + 75\% + 90\% + 85\%}{5} = 80\%\).
- Winter. \(\frac{30\% + 85\% + 40\% + 70\% + 80\%}{5} = 61\%\).
Winter has the lowest average survivability percentage across all seasons.
2. Let's calculate the average survivability in each region:
- Denver. \(\frac{85\% + 65\% + 70\% + 30\%}{4} = 62.5\%\).
- Miami. \(\frac{90\% + 95\% + 80\% + 85\%}{4} = 87.5\%\).
- Chicago. \(\frac{80\% + 70\% + 75\% + 40\%}{4} = 66.25\%\).
- Seattle. \(\frac{95\% + 85\% + 90\% + 70\%}{4} = 85\%\).
- Houston. \(\frac{87.5\% + 91.5\% + 85\% + 80\%}{4} = 86\%\).
Denver has the lowest average survivability percentage across all regions.
- Spring. \(\frac{85\% + 90\% + 80\% + 95\% + 87.5\%}{5} = 87.5\%\).
- Summer. \(\frac{65\% + 95\% + 70\% + 85\% + 91.5\%}{5} = 81.3\%\).
- Fall. \(\frac{70\% + 80\% + 75\% + 90\% + 85\%}{5} = 80\%\).
- Winter. \(\frac{30\% + 85\% + 40\% + 70\% + 80\%}{5} = 61\%\).
Winter has the lowest average survivability percentage across all seasons.
