Explanation:

Step1: Analyze the scatter - plot trend

By observing the scatter - plot, we can see that as the number of hours of video games increases, the number of hours of sleep decreases. We need to estimate the number of hours of sleep when the number of hours of video games is 1.

Step2: Locate the value on the x - axis

Locate x = 1 (1 hour of video games) on the x - axis of the scatter - plot. Then, look at the corresponding y - values (hours of sleep). The points seem to suggest that when x = 1, the y - value (hours of sleep) is around 7.

Answer:

d. 7 hours
