59. Cholesterol Suppose that the blood cholesterol level of all men aged 20 to 34 follows the Normal distribution with mean μ-188 milligrams per deciliter (mg/dl) and standard deviation σ 41 mg/dl. (a) Choose an SRS of 100 men from this population Describe the sampling distribution of . (b) Find the probability that x estimates μ within +3 mg/dl. (This is the probability that i takes a value between 185 and 191 mg/dl.) Choose an SRS of 1000 men from...

Testing blood cholesterol. The distribution of blood cholesterol level in the popnudation of young men aged 20 to 34 years is close to Nonal with mean 188 milligrams per deciliter (mg/dL) and standard deviation 41 mg/dL. You measure the blood cholesterol of 14 young men aged 20 to 34 years who have completed at least one marathon. The mean level is x = 172 mg/dL. Assume that σ is the same as in the general population. Use this information to...

The total cholesterol levels of a sample of men aged 35-44 are normally distributed with a mean of 220 milligrams per deciliter and a standard deviation of 38.2 milligrams per deciliter. (a) What percent of the men have a total cholesterol level less than 210 milligrams per deciliter of blood? (b) If 251 men in the 35-44 age group are randomly selected, about how many would you expect to have a total cholesterol level greater than 256 milligrams per deciliter...

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)...

The total cholesterol levels of a sample of men aged 35-44 are normally distributed with a mean of 209 milligrams per deciliter and a standard deviation of 36.8 milligrams per deciliter. (a) What percent of the men have a total cholesterol level less than 233 milligrams per deciliter of blood? (b) If 259 men in the 35-44 age group are randomly selected, about how many would you expect to have a total cholesterol level greater than 257 milligrams per deciliter...

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).
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...
