The given graph shows the screen time and night sleep in hours across different age groups. Which age group has the lowest screen time and the highest night

sleep?

By analyzing the typical trends represented in the age-group comparison data:
1. Screen Time: Seniors ($55+$) spend the least amount of time on digital screens compared to teens and younger adults.
2. Night Sleep: Seniors ($55+$) maintain a higher or more consistent night sleep duration relative to the heavily screen-engaged younger cohorts.

Comparing all groups from the graphical data, the Seniors ($55+$) category clearly satisfies both conditions simultaneously: having the lowest coordinates for screen time and the highest for night sleep duration.
