Question $3$ of $30$

Stacked

People gain weight when they take in more energy from food than they expend. James Levine and his collaborators at the Mayo Clinic investigated the link between obesity and energy spent on daily activity.

They chose $20$ healthy volunteers who didn't exercise. They deliberately chose $10$ who are lean and $10$ who are mildly obese but still healthy. Then they attached sensors that monitored the subjects' every move for $10$ days. The table presents data on the time $($in minutes per day$)$ that the subjects spent standing or walking, sitting, and lying down.

Time $($minutes per day$)$ spent in three different postures by lean and obese subjects
