Cholesterol levels among all adult (age 20 and older) females living in the United States are approximately Normally distributed with μ ≈ 200 mg/dl and σ ≈ 44 mg/dl. Find standardized scores associated with the following values, and then use the Standard Normal Table to find the cumulative percentage associated with each value:

A. x=200

B. x=240

standardized score

z= ??

z=??

percent below:

??

??

Based on the “percent below” calculations in problem 2, you can calculate the following:

_______% of adult American females have “desirable” cholesterol levels (below 200)

_______% of adult American females have “borderline high” cholesterol level (200 to 240)

_______% of adult American females have “high” cholesterol level (240 and above).

    Assume total cholesterol levels (TChol) are normally distributed with mean μ = 215 mg/dl and standard deviation σ = 30 mg/dl for the adult American population. That is, TChol ~ N(215, 302). Total cholesterol values of 240 mg/dl or greater are considered high; and levels in the range of 200 to 240 are called borderline high. a. What proportion of this population do we expect to find with high cholesterol? What proportion do we expect to find with borderline high...

    Background Cholesterol is a waxy, fatty substance found in the bloodstream. Serum Cholesterol measures the level of both good (HDL) and bad (LDL) cholesterol in your blood. For adults, a desirable cholesterol level will be between 125 mg/dL and 200 mg/dL. A borderline high cholesterol count is between 200 mg/dL and 239 mg/dL, and any reading from 240 mg/dL and beyond is considered high. High serum cholesterol levels could result in complications including stroke, heart attack, or coronary artery disease....

    High-density lipoprotein (HDL) is sometimes called the “good cholesterol” because high values are associated with a lower risk of heart disease. According to the American Heart Association, people over the age of 20 years should have at least 40 mg/dL of HDL cholesterol. HDL cholesterol levels for men have a mean of 46 mg/dL with a standard deviation of 13.6 mg/dL. Assume that the distribution is Normal. HDL levels of 60 mg / dL are believed to protect people from...
