As atherosclerosis is the commonest cause of arteriosclerosis, the two terms are often used interchangeably. Arteriosclerotic heart disease (ASHD), also called coronary artery disease (CAD) or coronary heart disease (CHD), refers to arteriosclerosis of heart or coronary arteries.he most common form of arteriosclerosis is atherosclerosis, in which fat, cholesterol and other substances build up on the inner walls of arteries and form hard structures called plaques or atheromas, which can restrict blood flow.
home / study / math / statistics and probability / definitions / central limit theorem. The central limit theorem states that given a distribution with mean Î¼ and variance Ï2, the sampling distribution of the mean approaches a normal distribution with mean Î¼ and variance , where n is the number of samples.
P90 means 90% of the estimates exceed the P90 estimate. It does not mean that the estimate has a 90% chance of occurring â that is a very different concept. The central limit theorem indicates that the P50 estimate has more chance of occurring than the P90 and P10 estimates.50 is defined as 50% of estimates exceed the P50 estimate (and by definition, 50% of estimates are less than the P50 estimate).
