Just answer the last question in the blank box the rest are corrwct The distribution of white blood cell count per cubic millimeter of whole blood is approximately Normal with mean 7600 and standard deviation 1715 for healthy patients. Complete parts (a) through (c) below. Include a Normal curve for each part. c. What is the probability that a randomly selected parson will have a white blood cell count of more than 10, 100? Choose the Normal curve that represents the probability that a randomly selected person will have a white blood cell count of more than 10,00. The probability that a randomly selected person will have a white blood cell count of more than 10, 100 is (Type an Integer or decimal rounded to three decimal places as needed.)

Explanation / Answer

mean= 7600 , std.deviation = 1715
P(X > 10100)

z = ( x - mean) / S
= ( 10100 - 7600) / 1715
= 1.46

Now, we need to find p(z > 1.46)
P(X > 10100) = P(z > 1.46) = 0.0725

The probability that a randomly selected person will have a white blood cell count of more than 10100 is 0.0725
