Angela recently discovered that the proportion of cat owners in Scranton, Pennsylvania, is 0.27.   Suppose Angela were to select a random sample of n = 100 Scranton residents and determine the proportion within the sample who are cat owners.  If this sampling process is repeated many times, we can build a sampling distribution.  We know in this case the sampling distribution will be Normal in shape and will have a standard deviation equal to approximately ___________.
