Question

The owner of a music store gathered data from several schools about the number of students in their concert and marching bands. The

scatter plot shows the data she gathered and the line of best fit.

Answer 1

25 students

Explanation:

Using the line of best fit, we want to deduce the number of students predicted to be in the marching band given that there are 35 in the concert band.

To deduce this, what we need to do is to go to the point where we have 35 on the concert band axis i.e the x-axis, then trace it upto the line of best fit.

Then from the line of best fit, now trace to the y-axis.

This gives an answer 25.
