   1. The problem statement, all variables and given/known data
   Consider an infinite population with the mean of 160 and a standard deviation of 25. A random size 64 is taken from this population.
   What does the standard deviation of the sample mean equal to?
   
   
   2. Relevant equations
   How do I answer this question without a given population size or proportion of the population?
   
   
   3. The attempt at a solution
