Hi,

Could anyone suggest a way to compare the following two set of data

data 1 :

Mean average=54.7 gram

standard deviation = 1.1 gram

x=50

Data 2:

Mean average=50.3 gram

standard deviation = 3.7 gram

x=50

I have tried the normal distribution on the first set of data only to end up getting z score of -4.27 ,I can change this to positive but the z score table end with 3-4 maximum limit

Is there any other method to compare these two set of data?
