Question 1140757: explain why a random sample of size 50 is to be preferred to a random sample of size 35 to estimate the value of the population. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! The larger the sample, all else being equal, the less the error in estimating the population mean. The error is an inverse function of the sqrt (n).
