According to her doctor, Mrs. Brown's cholesterol level is higher than only 10% of the females aged 50 and over. The cholesterol levels among females aged 50 and over are approximately normally distributed with a mean of 235 mg/dL and a standard deviation of 25 mg/dL. What is Mrs. Brown's cholesterol level? Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.

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...

Do you have enough “good cholesterol?” High-density lipoprotein (HDL) is sometimes called the “good cholesterol” because low values are associated with a higher risk of heart disease. According to the American Heart Association, people over the age of 20 years should have at least 40 milligrams per deciliter (mg/dl) of HDL cholesterol.40U.S. women aged 20 and over have a mean HDL of 55 mg/dl with a standard deviation of 15.5 mg/dl. Assume that the distribution is Normal.   PLEASE SHOW YOUR...

Calcium levels in people are normally distributed with a mean of 9.5mg / (dL) and a standard deviation of 0.4 mg / (dL) . Individuals with calcium levels in the bottom 10% of the population are considered to have low calcium levels. Find the calcium level that is the borderline between low calcium levels and those not considered low. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
