The level of cholesterol in the blood of women aged 20 to 55 in a particular country is normally distributed with mean 212 mg/dl and standard deviation 45.2 mg/dl.

The probability that a randomly selected such woman has cholesterol level between 200 and 240 mg/dl is about

0.337 is the probability that a randomly selected such woman has cholesterol level between 200 and 240 mg/dl.              

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 212

Standard Deviation, σ = 45.2

We are given that the distribution of level of cholesterol is a bell shaped distribution that is a normal distribution.

Formula:

P(cholesterol level between 200 and 240 )

0.337 is the probability that a randomly selected such woman has cholesterol level between 200 and 240 mg/dl.
