Question
Workers at a large toxic cleanup project are concerned that their white blood cell counts may have been reduced. Let x be a random variable that represents white blood cell count per cubic millimeter of whole blood in a healthy adult. Then μ = 7500 and
σ ≈ 1750.†
A random sample of
n = 50 workers
from the toxic cleanup site were given a blood test that showed
x = 6820.
(b) Compute
P(x ≤ 6820).
(Round your answer to four decimal places.)
