We want to compare fasting serum cholesterol levels of Filipino women to that of the other foreign women. Assume the cholesterol levels in 20- to 39-years old women in other foreign countries is normally distributed with mean µ = 190 mg/dl. Blood tests are performed on 100 female Filipinos in this age range rendered a sample mean cholesterol level of 181.52 mg/dl and standard deviation of 40 mg/dl. Conduct a test of hypothesis to determine whether Filipino women have lower average cholesterol levels than their foreign counterparts. Show all hypothesis testing steps.

Suppose we want to compare fasting serum-cholesterol levels among recent Chinese immigrants to Ghana with typical levels found in the general Ghanaian population. Suppose we assume cholesterol levels in women ages 21−40 in Ghana are approximately normally distributed with mean 190 mg/dL. It is unknown whether cholesterol levels among recent Chinese immigrants are higher or lower than those in the general Ghanaian population. Let’s assume that levels among recent female Chinese immigrants are normally distributed with unknown mean μ. Hence...

We want to compare the serum cholesterol levels of recent immigrants with the levels found in the general population of the US. It is known that the mean cholesterol level for a certain age group in the US is 190 mg/dL. A random sample of 100 recent immigrants of the same age group finds a mean of 181.52 mg/dL. Assume that a population standard deviation is 48.23. Test at the 5% level to see if the level for recent immigrants...

Too much cholesterol in the blood increases the risk of heart diseases. Young women are generally less afflicted with high cholesterol than other groups. The cholesterol levels for women aged 20 to 34 follow an approximately normal distribution with mean 190 milligrams per deciliter (mg/dl) and standard deviation 41 mg/dl. (a) Cholesterol levels above 270 mg/dl demand medical attention. What percent of young women have levels above 270 mg/dl? (b) Levels above 220 mg/dl are considered borderline high. What percent...

A serum cholesterol level above 250 mg/dl of blood is a risk factor for cardiovascular disease in humans.  At a medical center in St. Louis, a study to test the effectiveness of new cholesterol-lowering drug was conducted.  One hundred people with cholesterol levels between 250 mg/dl and 300 mg/dl were available for this study.  Fifty people were assigned at random to each of two treatment groups.  One group received the standard cholesterol-lowering medication and the other group received the new drug.  After taking the drug...

Calculate and comment on the LDL cholesterol values. What does the presence of small dense LDL mean? How many cardiovascular risk factors does this patient have? Discuss the type of hyperlipidaemia this patient is likely to have. What further tests and dietary/drug treatments would you recommend for this patient? Sample A is from a 35 year old male who visited his GP complaining of chest pain during exercise. An ECG taken at rest was normal but ischaemic changes developed on...

Suppose that a pharmaceutical company is interested in testing their new cholesterol medication and recruited 11 sets of identical twins with high blood pressures. For each twin, one was given the new drug and the other was given the old drug, then the reduction in LDL cholesterol level (unit: mg/dL) was measured after 6 months. Summary statistics of the amount of reduction are shown below. NOTE: Not all outputs given above are useful      n           x           s      New Drug    11    42...
