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).
The given question is:
The winning times (in seconds) in a speed-skating event for men can be represented by the formula T = 46.12 - 0.094x where x represents the year, with x=0 corresponding to 1920.
In 1983,
Substituting 63 for x in the given equation, we will get
