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...

Exercise4 It is known that the serum cholesterol levels of 18-year-old subjects population follow a Normal distribution with mean 196mg/dLi and a standard deviation 31 mg/dLi. For a subject selected at random, what is the probability that 1. The serum cholesterol level will be 220 or more? 2. The serum cholesterol level will be 230 or less? 3. The serum cholesterol level wil be between 130 and 160 (both included)? 4. At what value of serum cholesterol level will 70%...

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 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?

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).
Suppose the distribution of serum cholesterol values in undergraduate men is approximately normally distributed with mean...
Suppose the distribution of serum cholesterol values in undergraduate men is approximately normally distributed with mean mu = 190 mg/dl and standard deviation sigma = 40 mg/dl. a) What is the probability of selecting someone at random from this population who has a cholesterol value that is less than 180? b) You take a simple random sample of n = 49 individuals from this population and calculate the mean cholesterol of the sample. Describe the sampling distribution of x-bar? c)...
Assume total cholesterol levels (TChol) are normally distributed with mean μ = 215 mg/dl and standard...
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...

(1 point) Cholesterol levels for a group of women aged 20-29 follow an approximately normal distribution with mean 177.4 milligrams per deciliter (mg/dı). Medical guidelines state that women with cholesterol levels above 240 mg/dl are considered to have high cholesterol and about 3.5% of women fall into this category. 1. What is the Z score hat corresponds to the top 35% or the 96 5 th percenti e or the standard normal distribution? Round our answer to three decim a...

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...
