Answer:
0.033 is the probability that a teenage boy has a cholesterol level greater than 225.
Step-by-step explanation:
The following information is missing in the question:
Mean, μ = 170
Standard Deviation, σ = 30
Using the given information, we may solve the question as:
We are given that the distribution of distribution of cholesterol levels in teenage boys is a bell shaped distribution that is a normal distribution.
Formula:
a) P( cholesterol level greater than 225)
P(x > 225)
Calculation the value from standard normal z table, we have,
![P(x > 225) = 1 - 0.967= 0.033 = 3.3\%](https://tex.z-dn.net/?f=P%28x%20%3E%20225%29%20%3D%201%20-%200.967%3D%200.033%20%3D%203.3%5C%25)
0.033 is the probability that a teenage boy has a cholesterol level greater than 225.
