Question

The cholesterol levels of an adult can be described by a normal model with a mean of

187 mg/dL and a standard deviation of 28.

A. What percent of adults do you expect to have cholesterol levels over 210 mg/dL?

Answer 1

Answer #1

Given that, mean = 187 mg/dL

standard deviation = 28

A) We want to find, P(X > 210)

In percentage : 0.2061 * 100% = 20.61%

Therefore, the percent of adults who have cholesterol levels over 210 mg/dL is 20.61%
