... tests for one population mean. In these tests, we will consider only one population. In each case we will testing whether the true mean µ of the population is equal to a hypothesized mean µ0 . Thus the null hypothesis will always be of the form H0 : µ = µ0 . The alternative hypothesis will be of one ...
