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

How does altitude relate to song frequency of birds?

(1 point)

Altitude does not affect bird song frequencies.

Medium altitude has medium frequency songs.

Higher altitudes are correlated with higher song frequencies.

Higher altitudes are correlated with lower song frequencies

1 answer

The correct interpretation of the data provided is:

Higher altitudes are correlated with lower song frequencies.

This conclusion is based on the observation that as altitude increases (from low to medium to high), the number of birds singing below 1500 Hz decreases, indicating that higher altitudes are associated with lower frequencies of bird songs.
