Question

a flute instructor examined student progress. she found that playing a longer song does not necessarily mean that a student will have more or fewer wrong notes. what can she conclude? there is no correlation between song length and number of wrong notes. there is a correlation between song length and number of wrong notes. there may or may not be causation. further studies would have to be done to determine this. there is a correlation between song length and number of wrong notes. there is probably also causation. this is because there is likely an increase in the number of wrong notes with an increase in the song length.

Explanation:

The instructor found that playing a longer song does not necessarily mean more or fewer wrong notes. This implies that there may or may not be a correlation between song length and number of wrong notes. Further studies would be needed to determine causation. Just because there might be a correlation doesn't mean there is causation.

Answer:

There is a correlation between song length and number of wrong notes. There may or may not be causation. Further studies would have to be done to determine this.
