A summary of the seven steps of hypothesis testing
For almost every hypothesis test discussed in this book, statisticians have developed both a critical value rule and a p-value that can be used to perform the hypothesis test. Furthermore, it can be shown that for each hypothesis test the p-value has been defined so that we can reject the null hypothesis at level of significance α if and only if the p-value is less than α . We now summarize a seven-step procedure for performing a hypothesis test.
