Question

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) 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

Based on the data provided, it appears that as altitude increases, the frequency of bird songs decreases. Specifically:

• At low altitude (below 1500 Hz), there are 80 birds singing.
• At medium altitude (below 1500 Hz), there are 50 birds singing.
• At high altitude (below 1500 Hz), there are only 20 birds singing.

This pattern suggests that higher altitudes are correlated with lower song frequencies. Therefore, the correct response is:

Higher altitudes are correlated with lower song frequencies.
