The percentile values for the ordered list {15, 20, 35, 40, 50} One definition of percentile, often given in texts, is that the P-th percentile (<) of a list of N ordered values (sorted from least to greatest) is the smallest value in the list such that no more than P percent of the data is strictly less than the value and at least P percent of ...
[31] [32] The Urban-Brookings Tax Policy Center found that the bottom 20 percent of earners pay an average 2.9 percent effective income tax rate federally, while the richest 1 percent paid an effective 29.6 percent tax rate and the top 0.01 percent paid an effective 30.6 percent tax rate. [33]
In the US and many international publications, BAC levels are written as a percentage such as 0.08%, meaning that there is 0.08 g of alcohol for every 100 mL of blood. [1] [2] In different countries, the maximum permitted BAC when driving ranges from the limit of detection (zero tolerance) to 0.08%. [3] [2] BAC levels above 0.40% are ...
The determination of equality of opportunity in such an instance is based on mathematical probability: if equality of opportunity is in effect, then it is seen as fair if each of two applicants has a 50 percent chance of winning the job, that is, they both have equal chances to succeed (assuming of course that the person making the probability ...
MTBF can be calculated as the arithmetic mean (average) time between failures of a system. The term is used for repairable systems while mean time to failure (MTTF) denotes the expected time to failure for a non-repairable system. [1] The definition of MTBF depends on the definition of what is considered a failure.
For example, say a board has 7 members. "Majority" means "at least 4" in this case (more than half of 7, which is 3.5). But 50% + 1 is 4.5, and since a number of people can only be integer, "at least 50% + 1" would mean "at least 5". An example of the expression's misuse to refer to a majority is the 50+1 rule.
The second quartile (Q 2) is the median of a data set; thus 50% of the data lies below this point. The third quartile (Q 3) is the 75th percentile where lowest 75% data is below this point. It is known as the upper quartile, as 75% of the data lies below this point. [1]
