The Chi square test
... The chi square test uses the statistic chi squared, written χ2. The "test" that uses this statistic helps an investigator determine whether an observed set of results matches an expected outcome. In some types of research (genetics provides many examples) there may be a theoretical basis for expecti ...

hypothesis testing
... If television networks claim that the average length of time devoted to commercials in a 60-minute program is 12 minutes, we would use H0: = 12 minutes as our null hypothesis in a study regarding the average length of time devoted to commercials. Finally, if a repair shop claims that it should take ...

... Over the last couple of years I have been teaching MATH 132. In this process I have compiled a list of typed-up notes. Granted these notes are not perfect, nor necessarily complete. I have primarily taken the necessary information from each section and collected it into one place. For the most part ...

... with F(°)(s, t) = 1. Formula (1. 1) was given in [10] for the case /3 0. Applying the same kind of argument to the sequence Z*(t), defined as Z(k)(t) if Z(k)(t) = Z(t) and as so otherwise, yields a sequence of probability generating functions FkP which also converges to F and satisfies a relation si ...
