1000 adults who presented to their local emergency department with a possible heart attack had a blood sample collected for laboratory tests. It was later found that 300 of these people had not had a heart attack and the levels of triglycerides in the blood of this group were compared with the levels among the 700 who had had a heart attack giving the following results the odds ratio for the association between high triglycerides and heart attack is: Heart attack No heart attack High triglycerides 600 100 Low triglycerides 100 200 1) 2.0 2) 6.0 3) 12.0 4) 2.3 5) It cannot be calculated from the data shown

Low-density lipoprotein (LDL) is an important part of blood cholesterol test. LDL higher than 130mg/dl is a risk factor of developing cardiovascular disease. To prevent cardiovascular disease, a health center had a free blood cholesterol test for all the people older than 65 in the community. A total of eight people attended the blood screening and their blood test results are listed: LDL(mg/dl): 123, 120, 117, 142, 117, 128, 133, 136 How many standard deviations above the mean is the value considered a risk factor?

Cholesterol level in women Studies relating serum cholesterol level to coronary heart disease suggest that a risk factor is the ratio $x$ of the total amount $C$ of cholesterol in the blood to the amount $H$ of high-density lipoprotein cholesterol in the blood. For a female, the lifetime risk $R$ of having a heart attack can be approximated by the formula $$ R=2.07 \ln x-2.04 \quad \text { provided } \quad 0 \leq R \leq 1 $$ For example, if $R=0.65,$ then there is a $65 \%$ chance that a woman will have a heart attack over an average lifetime. (a) Calculate $R$ for a female with $C=242$ and $H=78$ (b) Graphically estimate $x$ when the risk is $75 \% .$
