We can set up a proportion to solve for the estimated number of patients who sleep 8 hours or more:
16/40 = x/700
Simplifying this proportion, we get:
0.4 = x/700
To solve for x, we can multiply both sides by 700:
x = 0.4 * 700
x = 280
Therefore, the estimated number of patients who sleep 8 hours or more each night is 280, which is option D.
Researchers at Jackson Hospital asked 40 randomly selected patients about their sleep habits. Sixteen reported sleeping 8 hours or more each night. If there are 700 patients in the hospital, estimate the number of patients who sleep 8 hours or more each night.
