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 Medium altitude has medium frequency songs. Medium altitude has medium frequency songs. Altitude does not affect bird song frequencies. Altitude does not affect bird song frequencies. Higher altitudes are correlated with higher song frequencies. Higher altitudes are correlated with higher song frequencies. Higher altitudes are correlated with lower song frequencies.
1 answer
Based on the provided data, as altitude increases, the frequency of bird songs decreases. At low altitude, 80 birds were singing below 1500 Hz, while at medium altitude, 50 were singing below 1500 Hz, and at high altitude, only 20 were singing below 1500 Hz.
Therefore, the correct response is: Higher altitudes are correlated with lower song frequencies.
