READ THE PROBLEM CAREFULLY AND ANSWER WHAT IS ASKED. SUPPOSE THAT BLOOD SUGAR LEVELS ARE NORMALLY DISTRIBUTED WITH A MEAN OF 100 MG/DL (MILLIGRAMS PER DECILITER) AND A STANDARD DEVIATION OF 10 MG/DL. DAVID HAS A BLOOD SUGAR LEVEL OF 85 MG/DL, KEVIN HAS A BLOOD SUGAR LEVEL OF 110 MG/DL, AND ARNOLD HAS A BLOOD SUGAR LEVEL OF 95 MG/DL. CALCULATE THE Z-SCORES OF DAVID, KEVIN, AND ARNOLD AND DETERMINE WHICH OF THE THREE IS EXACTLY 1 STANDARD DEVIATION AWAY FROM THE MEAN. (SHOW YOUR SOLUTIONS)  1. THEN, WHAT IS THE CONCLUSION?
