Question

Based upon the scatter plot below, what would you predict the line of best to be in terms ofthe y-intercept? In other words, what % of muscle tone would you expect for someone whonever works out?

Answer 1

Answer: 2%

Explanation:

The y intercept is the value of y at the point where the line touches the y axis.

Looking at the plot, If we extend the line so that it touches the y axis, the point of intersection would most likely be y = 2. Thus, the y intercept is 2

The y axis represents the muscle tone in %

The x axis represents number of hours of exercise.

At x = 0, y = 2

Thus is the y intercept. It means that for zero hours of workout, the muscle tone is 2%.

Thus, the expected % of muscle tone for someone who doesn't work out is 2%
