In statistics there are two kinds of means: population mean and sample mean. A population mean is the true mean of the entire population of the data set while a sample mean is the mean of a small sample of the population.
: the null hypothesis. : the alternative hypothesis. (4) Test statistic. The test statistic is a statistic that can be computed from the data of the sample. Examples are z and t which may be computed in several ways depending on the data and the hypotheses to be tested.t only indicates whether the hypothesis is supported by the data or not. Example of test statistic. Testing the mean using z, = relevant statistic--sample mean. = hypothesized parameter--population mean. = standard error of which is the relevant statistic. This all depends on the assumptions being correct.
