A cholesterol screening finds that a person's blood serum has 38 mg/dL HDL and 190 mg/dL LDL a. Are these values within the normal range? o Yes No b. How many grams of HDL are present in 3.0 mL of the serum? the tolerance is +/-29% c. How many micrograms of LDL are present in 2.5 x 10-4 L of the serum? the tolerance is +/-2% d. What is the LDL/HDL ratio? Is this value considered to be healthy? No...

Patient's total serum cholesterol concentration is Cpatient- (Apatient Astandard) x Cstandard (0.237/0.331) x 200 mg/dL 143.2 mg/dL Therefore 143.2 mg/dL
The distribution of serum cholesterol levels for the general population of adult males in the United...
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...

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

Serum cholesterol is an important risk factor for coronary disease. Suppose that serum cholesterol is approximately normally distributed with mean 216 mg/dL and a standard deviation of 46.32 mg/dL. a. Cholesterol levels in the top 18% are classified as high enough to warrant risk for heart disease. What cholesterol level corresponds to this cut-off? z = ____________ cholesterol = _________ mg/dL b. Suppose cholesterol levels in the bottom 36% are classified as normal. What cholesterol level corresponds to a normal...
The cholesterol levels of adult males are approximately normally distributed with a mean of 224 mg/dl,...
The cholesterol levels of adult males are approximately normally distributed with a mean of 224 mg/dl, and a variance, o', of 521. Some researchers claim that the variance of cholesterol levels of adult males is less than 521. A sample of 15 adult males' blood tests had a mean of 222.5 mg/dL and a variance of 192. Is there enough evidence to conclude, at the 0.05 level of significance, that the variance of cholesterol levels of adult males is less...

a clinical report gave the following data from a blood analysis: iron 39 mg/dl, calcium 8.0 mg/dl cholesterol 224 mg/dl. how many grams of calcium are present in the blood of the patient if the blood volume is 2.6 liters? Please show all work thank you

(6 points) Total cholesterol levels less than 2.00x 10 milligrams per deciliter (mg/dL) are considered desirable for adults. Use this border-line concentration to calculate how many grams of total cholesterol the individual's body may contain if the total blood volume of the individual is 5.4 L. 8.

The serum cholesterol levels of children aged 11 to 14 years follows a normal distribution with mean 163 mg/dl and standard deviation a 20 mg/dl. In a population of 1000 of these children, how many would be expected to have serum cholesterol levels between 164 and 190? between 147 and 1697? What integral gives the probability that a child has a serum cholesterol levels between 164 mgidl and 190 ma/di? dx (Type exact answers, using x as needed.) f children...

3. Assume the cholesterol levels of adult American women can be described by a Normal model with a mean of 188 mg/dL and a standard deviation of 24. a. What percent of adult women do you expect to have cholesterol levels over 200 mg/dL? b. What percent of adult women do you expect to have cholesterol levels between 150 and 170 mg/dL? C. Estimate the interquartile range of the cholesterol levels. d. Above what value are the highest 15% of...
