Correct answer is (a) True

Easiest explanation: Assuming Gaussian distribution, the mean statistical error means that 67% of tests fall into the interval (n +or- under-root n) with 33% of the measurements greater than that. To obtain the statistical error, the instrument reading should be multiplied by the scaling factor of the counter. This will yield the value of n.
