BHS 220 Module 4 - Case-INTRODUCTION TO HYPOTHESIS TESTINGNameCourseInstructorDate ProbabilityProbability is an integral component of statistics, with the frequency of an outcome, whereby determining the relative frequency of a population (Cook et al., 2004). When there is no prior knowledge about the possible outcomes of an event, then there is an assumption that all outcomes have an equal chance of occurring. The outcomes are mutually exclusive while the events are independent. Probabilities representing the possible outcomes help to demonstrate probability distributions, with the shape of the probability distribution curve influenced by the mathematical distribution (Cook et al., 2004). In the standard normal distribution, it is assumed that the population is truly homogenous when calculating for the Z-test. Furthermore, the underlying distribution is assumed to be normal, with sample distribution being homogenous (Michelson & Schofield, 2002).Probability relates to the likelihood of an event happening, where a value of 0 indicates that there are no chances fro the event to occur, while 1 indicates that there is certainty that the event will definitely occur. The history of probability was started with the need to utilize computing methods to improve chances of winning during gambling games in France during the 1...
