STATE: Cardiovascular disease is a major cause of death and illness worldwide, with high blood pressure and high LDLcholesterol both being established risk factors. Because most cardiovascular events occur in persons with average riskfactors. Because most cardiovascular events occur in persons with average risk and no previous cardiovascular diseasehistory, the present research examined the simultaneous use of both blood pressure reducing drugs and cholesterolreducing drugs on this population, rather than focusing on only those on only those at high risk. Subjects included men atleast 55 years old and women at least 65 years old without cardiovascular disease who had at least one additional riskfactor besides age, such as recent or current smoking, hypertension, or family history of premature coronary heartdisease. Those with current cardiovascular disease were excluded from the study. Subjects were randomly assigned to thetreatment (cholesterol and blood pressure reducing drugs) or a placebo, and the number suffering the primary outcome ofa fatal cardiovascular event, a nonfatal myocardial infarction or a nonfatal stroke, were observed.

Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.

Normal Distribution

Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
