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...

2. The blood cholesterol level of men aged 20 to 34 is normally distributed with a mean of 188 mg/dl and a standard deviation of 41 mg/dl. a) (5 pts.) Find the probability a man in this age range has a blood cholesterol between 180 and 205. b) (5 pts.) A random sample of 100 men in this age range is taken. What is the probability the average for these men is greater than 189?

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 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...

A government sample survey plans to measure the LDL (bad) cholesterol level of an SRS of men aged 20 to 34. Suppose that in fact the LDL cholesterol level of all men aged 20 to 34 follows the Normal distribution with mean μ = 119 milligrams per deciliter (mg/dL) and standard deviation σ = 25 mg/dL. Use Table A for the following questions, where necessary. (a) What is the probability that x takes a value between 116 and 122 mg/dL?...

2. Shelia's doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation both in the actual glucose level and in the blood test that measures the level. A patient is dlassified as having gestational diabetes if the glucose level is above 140 milligrams per deciliter (mg/di) one hour after a sugary drink. Shelia's measured glucose level one hour after the sugary drink varies according to the Normal distribution with μ-125 mg/dl...
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)...

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).
