All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample to make
a statistical inference about the mean of the normally distributed population from which it was drawn?

The margin of error is multiplied by 0.5
The margin of error is multiplied by V2
The margin of error is multiplied by 0.5.
The margin of error is multiplied by 2.
