Let x be a random variable that represents white blood cell count per cubic milliliter of whole blood. Assume that x has a distribution that is approximately normal, with mean μ = 6050 and estimated standard deviation σ = 2100. A test result of x < 3500 is an indication of leukopenia. This indicates bone marrow depression that may be the result of a viral infection.
(a) What is the probability that, on a single test, x is less than 3500? (Round your answer to four decimal places.)
(b) Suppose a doctor uses the average x for two tests taken about a week apart. What can we say about the probability distribution of x?
The probability distribution of x is approximately normal with μx = 6050 and σx = 1050.00.
The probability distribution of x is approximately normal with μx = 6050 and σx = 1484.92.
The probability distribution of x is approximately normal with μx = 6050 and σx = 2100.
The probability distribution of x is not normal.
What is the probability of x< 3500? (Round your answer to four decimal places.)
(c) Repeat part (b) for n = 3 tests taken a week apart. (Round your answer to four decimal places.)
(d) Compare your answers to parts (a), (b), and (c). How did the probabilities change as n increased?
The probabilities decreased as n increased.
The probabilities increased as n increased.
The probabilities stayed the same as n increased.
If a person had x< 3500 based on three tests, what conclusion would you draw as a doctor or a nurse?
It would be a common event for a person to have two or three tests below 3,500 purely by chance. The person probably has leukopenia.
It would be a common event for a person to have two or three tests below 3,500 purely by chance. The person probably does not have leukopenia.
It would be an extremely rare event for a person to have two or three tests below 3,500 purely by chance. The person probably does not have leukopenia.
