Question

A city collects data over five years on bicycle sales and air quality (measured by Air Quality Index, or AQI). The data is shown below:

The city concludes that increasing bicycle sales directly improves air quality.

Which of the following best evaluates the city’s conclusion?

Options

Increasing bicycle sales directly improves air quality by reducing car emissions.

The correlation is coincidental; there is no relationship between bicycle sales and air quality.

There is a correlation between bicycle sales and improved air quality, but other factors, such as environmental policies or reduced industrial emissions, may also play a role.

Bicycle sales are irrelevant to air quality improvement, as AQI improvement happens naturally over time.
