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?

Higher altitudes are correlated with higher song frequencies.
Higher altitudes are correlated with lower song frequencies.
Higher altitudes are correlated with lower song frequencies.
Medium altitude has medium frequency songs.
Medium altitude has medium frequency songs.
Altitude does not affect bird song frequencies.
1 answer
The correct response based on the data provided is:
Higher altitudes are correlated with lower song frequencies.
This is supported by the data showing that as altitude increases, the number of birds singing below 1500 Hz decreases: at low altitude, 80 birds sing below 1500 Hz, at medium altitude, 50 birds sing below 1500 Hz, and at high altitude, only 20 birds sing below 1500 Hz. This indicates that higher altitudes are associated with lower frequencies of bird songs.
