Solution: Since we are finding a z-score, we are dealing with the standard normal curve, so the mean is 0 and the standard deviation is 1. Now, to use the MINITAB procedure, we must know the area to the lefty Since the area to the right of the z-score is 0.68, the area to the left is given by 1-0.68 0.32. Input the following to MINITAB: Nd D n Op Out Co Discussion Topics: 1. Copy and paste the inverse cumulative distribution function figure. 2. What is the z-score that has an area of 0.68 to its right?
