Bayes’ theorem describes the relationships that exist within an array of simple and conditional probabilities. For example: Suppose there is a certain disease randomly found in one-half of one percent (.005) of the general population. A certain clinical blood test is 99 percent (.99) effective in detecting the presence of this disease; that is‚ it will yield an accurate positive result in 99 percent of the cases where the disease is actually present. But it also yields false-positive results in 5

The Poisson probability distribution‚ named after the French mathematician Siméon-Denis. Poisson is another important probability distribution of a discrete random variable that has a large number of applications. Suppose a washing machine in a Laundromat breaks down an average of three times a month. We may want to find the probability of exactly two breakdowns during the next month. This is an example of a Poisson probability distribution problem. Each breakdown is called an occurrence in Poisson

A Density Study Del Valle‚ Mariel Allegra Abstract This experiment is composed of three parts. The purpose of the first experiment is to find the density of dry ice by using the method of displacement volume. Before the experiment‚ it was thought that the density would decrease over time due

or less than the volume of water it displaces. The second objective of the experiment was to produce a value for water density. It was expected that when additional mass was added to a floating vessel‚ it would displace more fluid and the increasing submerged volume of water could be measured‚ and a value for water density could be calculated using the equation . The density of pure water was assumed to measure 1000 kg/m³ at 4°C however it was also assumed that the tap water used in the experiment

The Mean and Median: Measures of Central Tendency The Mean and the Median The difference between the mean and median can be illustrated with an example. Suppose we draw a sample of five women and measure their weights. They weigh 100 pounds‚ 100 pounds‚ 130 pounds‚ 140 pounds‚ and 150 pounds. To find the median‚ we arrange the observations in order from smallest to largest value. If there is an odd number of observations‚ the median is the middle value. If there is an even number of observations

Probability Distribution Essay Example Suppose you flip a coin two times. This simple statistical experiment can have four possible outcomes: HH‚ HT‚ TH‚ and TT. Now‚ let the random variable X represent the number of Heads that result from this experiment. The random variable X can only take on the values 0‚ 1‚ or 2‚ so it is a discrete random variable Binomial Probability Function: it is a discrete distribution. The distribution is done when the results are not ranged along a wide range‚ but are

The physical environment has determined to some extent‚ the distribution and density of Australia’s population. Discuss. People do not live evenly spread through the world. Australia is one of the counties that considered has a low population density. This is due to approximately 23 million population were distributed unevenly. Besides the physical environment‚ there are also a variety of other factors that have actually worked together to distribute in the Australia’s population that cannot be

Determining the accuracy of varieties of pipettes by weighing and finding the density of a liquid Abstract Different varieties of pipettes (P100‚ PR1000 pipettors and a serological pipette) along with a weighing balance was used in this investigation to check the density of an unknown liquid by first finding out what the liquid weighed and plotting a graph of the mass in grams against the volume of the liquid used in micro litres (µl) and finding the gradient of the graph (∆Y/∆X). Most of the
