Unformatted text preview: Problem No._______________________________ Power (or β ) Calculation Template (9.23.09) 1. Since we generally end up with finding an area under a curve as the answer, call that area A , and write for your problem below: A = Pr{Accept Ho or Reject Ho (pick one) | H1 true} A = _____________________________________ 2. Next substitute in for the phrase to the left of the “|” the decision rule region (see H.T. Step 5) and substitute to the right of the “|” ” θ = a”, where “ θ ” is the unknown parameter and “a” is the value of the unknown parameter at which we are making this evaluation. = _____________________________________ 3. Unless you know the distribution under “ θ = a”, you will next substitute for the observed statistic in the expression to the left of the “|” using its definition (see H.T. Step 2c). = _____________________________________ 4. Next solve for the statistic in the expression to the left of the “|”. = _____________________________________ = _____________________________________ 5.State the relevant distribution fact: Using D.F. ___ : __________________________ Which in this case, substituting the known values and with “ θ = a”, the DF for our problem becomes: DF: ______________________________________ 6.a. Below, draw a number line, label the variable 6....
