a) What is the standard deviation of this population ? ( 2 decimal places).
b) What would the standard deviation of the mean be for a sample size of n= 14 from this population ? (to three decimal places).
c) What would the standard deviation of the sum be for a sample size of n= 14 from this population ? ( to two decimal places).
d) For what size sample would the variance of the mean equal 1?
e) For what size sample would the standard deviation of the mean equal 3?
