Question

Question 1 of 10

All else being equal, a study with which margin of error would give you the
most confidence in the results?
OA. ±20 percentage points
OB. +5 percentage points
O C. 15 percentage points
D. ±10 percentage points

Answer 1

±5 percentage points

Explanation:

i can't really understand what was equal, because there isn't data about it.

But in case you really don't know it, the lower the margin of error of something is, the more confident you are it is correct, because the lower the error is, the more accurate it is to the theoretical result, so in this case it is ±5.
