Consider the distribution of serum cholesterol levels for all 20 to 74 year old males living in the United States. The mean of this population is 211 mg/100 ml, and the standard deviation is 46 mg/100 ml. How large would the samples need to be for 95% of their means to lie within ±5 mg/100 ml of the population mean?

The serum cholesterol levels for 20-24 year old males in the US has mean 180 mg/100ml and standard deviation σ = 46 mg/100ml. We are interested in the mean cholesterol level of the larger population of 20-74 old males, say µ. Suppose, we have a random sample of size 25 from the larger population. We want to test the following hypotheses at significance level α = 0.01: H0 : µ = 180, HA : µ > 180 a) What is...

(a) Find the probability that the serum cholesterol level of a randomly chosen 14-year-old boy exceeds 230. (b) In a middle school there are 300 14-year-old boys. Find the probability that at least 8 boys have a serum cholesterol level that exceeds 230. 2) Suppose that the service life, in years, of a hearing aid battery is a random...

Cholesterol levels for women aged 20 to 34 follow an approximately normal distribution with mean 185 milligrams per deciliter (mg/dl). Women with cholesterol levels above 220 mg/dl are con- sidered to have high cholesterol and about 18.5% of women fall into this category. What is the standard deviation of the distribution of cholesterol levels for women aged 20 to 34?

The distribution of serum cholesterol levels for the general population of adult males in the United States is normal with a mean of 211 mg/dL and a standard deviation of 46 mg/dL. A researcher wishes to know if adult males who are hypertensive and who smoke differ significantly from this general population with regards to their serum cholesterol levels. The researcher randomly selects 25 adult male hypertensive smokers, measures their serum cholesterol levels, and calculates a mean of 217 mg/dL...

Cholesterol levels for women aged 20 to 34 follow a normal distribution with mean 185 milligrams per deciliter (mg/dl) and standard deviation 40 mg/dl. What is the probability of randomly selecting a woman in this age range with a cholesterol level below 140 mg/dl? Note: As always, please give this probability in decimal form (i.e., 0.xxx).

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....
