Six Sigma Tools for Testing Statistical SignificanceName:Institution:Date:Hypothesis testing is a statistical method that is used to determine whether a hypothesis regarding a certain perimeter in a given amount of data usually referred to as a population, using data measured in a sample is true CITATION Pec11 l 1033 (Peck, Olsen, & Devore, 2011). The test aims at determining the likelihood of a certain statistical sample could be selected and the hypothesis tested is true. It is also known as significance testing and it is a process used to select samples and get more information of its characteristics in a sample CITATION Pec11 l 1033 (Peck, Olsen, & Devore, 2011).Hypothesis testing involves 4 steps that are; identification of a hypothesis to be tested, determining rationale by which the hypothesis will be determined to be true or not, select a random sample and get the mean, and compare the sample observation to what we expect as true or not CITATION Pec11 l 1033 (Peck, Olsen, & Devore, 2011).Several methods are applied in hypothesis testing that depends on the number of variables used and t...
