It is well documented that cholesterol over 200 is a risk factor in developing heart disease for both men and women (www.livestronge.com, January 11, 2011). Younger men are known to have higher cholesterol levels than younger women; however, beyond the age of 55, women are more likely to have higher cholesterol levels. a recent college graduate working at a local blood lab has access to the cholesterol data of 50 men and 50 women in the 20 - 40 age...

A study was conducted at an American medical center and heart-attack incidents. A random sample of 30 heart-attack patients had their cholesterol levels measured two days after the attack. In addition, cholesterol levels were measured for a control group of 30 people who had not had a heart attack. The unitsf cholesterol measurement are mg/dL of blood. The two data sets are below regarding blood cholesterol levels DATA SET 1: HEART ATTACK GROUP (Assume that σ=46.63). 270 236 210 142...

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....

3. Serum cholesterol levels above 200 mg/dl are considered high. A study is being planned to determine if the mean cholesterol level for adult Canadians exceeds 200. If a t-test is to be used with α= 0.05, what sample size is required to detect a mean cholesterol level as high as 218 with power .95? An earlier study estimated the standard deviation of cholesterol levels among Canadian adults to be about 58.2

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...
