To estimate the number of patients who sleep 8 hours or more each night, we can set up a proportion based on the data given.
The proportion is as follows:
(22 patients who sleep 8 hours or more) / (50 patients surveyed) = (x patients who sleep 8 hours or more) / (600 total patients)
We can solve for x by cross-multiplying and then dividing:
22 * 600 = 50 * x
13,200 = 50x
x = 13,200 / 50
x ≈ 264
Therefore, the estimated number of patients who sleep 8 hours or more each night is 264.
The correct answer is d-264.
