ovascula ase Serum cholesterol is an important risk factor for coronary disease. We can show that serum cholesterol is approxi- mately normally distributed, with mean = 219 mg/di and standard deviation = 50 mg/dL. '5.14 If the clinically desirable range for cholesterol is < 200 mg/dL, what proportion of people have clinically desirable levels of cholesterol? '5.15 Some investigators believe that only cholesterol evels over 250 mg/dL indicate a high-enough risk for heart disease to warrant treatment. What proportion of the popu- ation does this group represent? '5.16 What proportion of the general population has borderline high-cholesterol levels–that is, > 200 but < 250 mg/dL?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
