All else being equal, a study with which of the following error ranges would be the most reliable?
a.7 percentage points
b.12 percentage points
c.2 percentage points
d.17 percentage points

The correct option is C

Step-by-step explanation:

Percentage point : It is defined as a unit for the arithmetic difference of two percentages and greater the difference more will be the error range.

So, the most reliable error range is the one whose percentage point is minimum.

Now, among the provided options , 2 percentage points is minimum so it will be the most reliable error range.

Hence, Option C. 2 percentage points is correct
