Question

1. eight college students recorded how many hours they exercised every week. then they measured their pulse (heartbeats per minute) while they were resting. what does the graph show? graph: pulse vs. exercise, with x-axis exercise/week (hrs) and y-axis pulse (beats/min), scatter plot with points options: - the more you exercise, the higher your resting pulse. - the more you exercise, the lower your resting pulse. - exercise has no effect on your resting pulse. - all of the college students had the same resting pulse.

Explanation:

By observing the scatter plot (Pulse vs. Exercise), as the "Exercise/week (hrs)" (x - axis) increases, the "Pulse (beats/min)" (y - axis) generally decreases. So the trend shows that more exercise is associated with a lower resting pulse. The other options are incorrect: the first option says higher pulse with more exercise (opposite of trend), the third says no effect (but there is a negative trend), and the fourth says all have same pulse (points have different y - values).

Answer:

The more you exercise, the lower your resting pulse.
