Medical: Blood Protoplasm Porphyrin is a pigment in blood protoplasm and other body uids that is signicant in body energy and storage. Let x be a random variable that represents the number of milligrams of porphyrin per deciliter of blood. In healthy adults, x is approximately normally distributed with mean μ = 41 and standard deviation σ = 9. What is the probability thata) x is less than 55?

Ответ:
0.9401 is the required probability.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 41
Standard Deviation, σ = 9
We are given that the distribution of number of milligrams of porphyrin is a bell shaped distribution that is a normal distribution.
Formula:
P(x is less than 55)
Calculation the value from standard normal z table, we have,
0.9401 is the probability that x is less than 55.
