The margin of error is multiplied by 2
The margin of erroris multiplied by 05.
The margin of erroris multiplied by 2

Answer 1

It multiplies by 2

Since the sample size is half the size of the previous

the margin of error is also multiplied by by 1/(1/2) or 2 so the margin of error is larger ;)

answer: multiplies by 2

It’s D, I might be wrong
