SH, "Create an "ILLUSION" that there was a difference between the U.S. and Canada. "

Let's see...."A" has 4 times the numer of cases in a herd 1/7th the size of "B"..... but you say that a difference is only an ILLUSION.  Let me give you some advice, don't apply for a job as in insurance underwriter, statistician, or anything requiring math over 8th grade algebra.
