a towns snowfall in december averages 13 inches with a standard diviation of 8 inches while in february the average snowfall is 40 inches with a standard deviation of 13 in which month is it more likey to snow 32 inches. explain

statistics 
JJ,
13 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
3240 = 8 divided by 13 to
get z = .615
These give you the exact values. February is still the answer.
