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?

Responses

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

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

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

Medium altitude has medium frequency songs.

Answer 1

Based on the data collected, it seems that as altitude increases, the number of birds singing below 1500 Hz decreases. Specifically, 80 birds at low altitude, 50 at medium altitude, and only 20 at high altitude are singing below this frequency. This suggests a trend where higher altitudes are correlated with lower song frequencies.

Thus, the correct response would be:

Higher altitudes are correlated with lower song frequencies.
