2. The steps of hypothesis testing You intend to draw a random sample in order to test a hypothesis about an unknown population mean. You will use a hypothesis test. A description of each of the steps of a hypothesis test follows, but they may be specified in the incorrect order. Specify the correct order of the steps. Determine the null and alternative hypotheses. Select a level of significance. Make a decision about the unknown population. Select a sample and compute the z-score for the sample mean.
