Given : The mean per capita consumption of milk per year : 
Standard deviation : 
Sample size : 
Let 
be the sample mean.
The formula for z-score in a normal distribution :
For 
The P-value = 
Hence, the probability that the sample mean would be less than 137.01 liters is 0.0192 .
The 90th percentile is 1.2816 standard deviations from the mean. That tells you the standard deviation is ...
... (40 in - 38 in)/(1.2816) ≈ 1.56 in
