Answer:
The flute instructor can conclude that the length of the song does not have a direct variation or correlation with the number of incorrect notes.
Step-by-step explanation:
Direct variation and correlation means that as the "x" variable increases, the "y" variable will change according to it.
If the flute instructor took numerical data, for example, made a chart, and graphed it, then he would not find a trend.
It would probably look like this (see first photo). The plotted points are all over the place. ("x" is the song length, "y" is the number of incorrect notes).
If there was a correlation, then the data would look more like a straight line (see second photo).
