All else being equal, a study with which of the following error ranges would be the most reliable?
a)+ 7 percentage points
b)+ 22 percentage points
c)+ 12 percentage points
d)+ 17 percentage points

Option: A is the correct answer.

A) +7 percentage points.

Step-by-step explanation:

A solution is said to be reliable if it has a low error and thus leads to a better approximation.

Hence, the less is the error of the the more closer estimation we get to the actual value of the expression.

If the error is much higher than the solution is not considered as reliable.

Hence, all else being equal the error range that would be most reliable is:

A) +7 percentage point.
