The coefficient of variation formula is:
CV+=+%28Standard+_Deviation%2FMean%29+%2A+100
CV=%28sigma%2Fmu%29%2A100.......................in your case sigma=1, and mu=6
CV=%281%2F6%29%2A100
CV=50%2F3
CV=16.666666666666666666666666666666666666666666666666666666666666666 round
CV=16.7 percent

answer: 16.7 percent
