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

Question

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)
Responses

Higher altitudes are correlated with lower song frequencies.
Higher altitudes are correlated with lower song frequencies.

Altitude does not affect bird song frequencies.
Altitude does not affect bird song frequencies.

Medium altitude has medium frequency songs.
Medium altitude has medium frequency songs.

Higher altitudes are correlated with higher song frequencies.
Higher altitudes are correlated with higher song frequencies.

Answer 1

The correct response based on the provided data is:

Higher altitudes are correlated with lower song frequencies.

This is supported by the data collected, which shows that as altitude increases from low to high, the frequency of bird songs decreases (80 below 1500 Hz at low altitude, 50 below 1500 Hz at medium altitude, and 20 below 1500 Hz at high altitude).
