Jacob distributed a survey to his fellow students asking them how many hours they'd spent playing sports in the past day. he also asked them to rate their mood on a scale from 000 to 101010, with 101010 being the happiest. a line was fit to the data to model the relationship.

Using the linear function given, it is found that the best estimate of the average change in mood rating associated with a 1 hour increase in hours playing sports is of 1.5 points.

A linear function is modeled by:

In which:

In this problem:

The equation is:

The slope is of , hence, the best estimate of the average change in mood rating associated with a 1 hour increase in hours playing sports is of 1.5 points.
