Q13: What is the raw score on Test 2 below which 97.5 percent of the scores can be found (i.e., the percentile point)? Round to two decimal places if necessary. Hint: Sketch and annotate a z distribution to clarify the portion of the distribution you are trying to quantify. Now, find the z score closest to the point below which 97.5 percent of the values fall. Last, write down the z equation with the values for z, µ, and o in their proper places and solve for X.
