Any inference procedure involves four steps. Know what they are and that they must always be there.
And never forget that your conclusion in context (Step 4) must be linked to Step 3 in some way.
- When doing inference problems, remember that you must show that the conditions necessary to do the
procedure you are doing are present. It is not sufficient to simply declare them present. - Be clear on the concepts of Type I and Type II errors and the power of a test.
- If you are required to construct a confidence interval, remember that there are three things you must
do to receive full credit: justify that the conditions necessary to construct the interval are present;
construct the interval; and interpret the interval in context. You’ll need to remember this; often, the
only instruction you will see is to construct the interval. - If you include graphs as part of your solution, be sure that axes are labeled and that scales are
clearly indicated . This is part of communication.
