Q1) High value of serum cholesterol is thought to be risk factor for heart diseases. National cholesterol education program of national institutes of health in 1987 stated that recommended value for serum cholesterol is below 200mg/dl and value between 200 and 240 is considered to be borderline. Value above 240 may point to problem and NCEP recommended that lipoprotein analysis must be carried out. Based on these data it seems that many non hispanic whites have serum cholesterol values that are too high, particularly woem. Medical literatures also ultimately beginning to identify homocysteine is a very significant risk factor for heart disease, even among people with normal levels of serum cholesterol

a) Provide some possible reasons why non hispanic white males have higher mortality from heart and cerebrovascular diseaes when it seems from these data that non hispanic white females must have higher rates.

b) Give a possible description why serum cholesterol values for older males are lower than for younger males and reverse is true for females.
