Question 1138472: Increasing the sample size while keeping the same confidence level has what effect on the margin of error?
A. Decreases the margin of error and hence increases the precision
B. Increases the margin of error and hence decreases the precision
C. Increases the margin of error and hence increases the precision
D. Decreases the margin of error and hence decreases the precision
E. None of the above Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! A. Decreases the margin of error, so that the precision is increased. It does so as an inverse function of the square root of n.
