Problem 13E
The serum zinc level X in micrograms per deciliter for males between ages 15 and 17 has a distribution that is approximately normal with μ = 90 and σ = 15. Compute the conditional probability P(X > 120 |X > 105).
ANSWER:
Step 1 of 2:
Given that X denotes the serum zinc level (in micrograms) per deciliter for males of age group 15 to 17.
Also X has approximate normal distribution with mean =90 and standard deviation =15.
We have to find the value of P(X>120|X>105).
