**JJ**, Saturday, February 9, 2013 at 1:38pm13 and add 8 = 21 add 8 = 30 and add 8 =38. So, 32 falls between 2 and 3 standard deviations.

40 - 13 = 27, 32 falls within one standard deviation.

February is more likely.

You could also take 32 -13 =19 and divide by 8 to get z = 2.375

32-40 = -8 divided by 13 to

get z = -.615

These give you the exact values. February is still the answer.
