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 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...

The serum cholesterol levels for 20-24 year old males in the US has mean 180 mg/100ml and standard deviation σ = 46 mg/100ml. We are interested in the mean cholesterol level of the larger population of 20-74 old males, say µ. Suppose, we have a random sample of size 25 from the larger population. We want to test the following hypotheses at significance level α = 0.01: H0 : µ = 180, HA : µ > 180 a) What is...
