transformation of that will give it a mean of zero and a variance of one (ie.‚ standardize ). Let the transformed variable be named Z. We desire μz=0‚ σ2z=1. This means 0=a+b μX and b2 σ2X=1. One solution to this system of equations is b=1/12 and a=-5/2. Of course‚ if you recognized the fact that our standard Z-transformation accomplishes precisely this‚ you could write the transformation as . 1b. Find the probability that . Convert X into a standard normal via Z= . For X=18‚ Z=-1. For X=36
