Infinite population question

  1. Apr 1, 2010 #1
    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

    Look in your textbook for the distribution of sample means. It might also be under standard error of the mean.
