Data is collected on the frequency of mountain bird songs at three different elevations. Data is collected from 100 birds at each elevation.

Low altitude: 80 below 1500 Hz
Medium altitude: 50 below 1500 Hz
High altitude: 20 below 1500 Hz

1 answer

Based on the provided data, the correct response is:

Higher altitudes are correlated with lower song frequencies.

This conclusion is drawn from the observation that as altitude increases (from low to medium to high), the number of birds singing below 1500 Hz decreases significantly.
