A zscore of z 200 indicates a position below the mean by 2

A z-score of z = -2.00 indicates a position
  1. below the mean by 2 points
    below the mean by 2 times the standard deviation
    above the mean by 2 points
    above the mean by 2 times the standard deviation

A z-score of z = -2.00 indicates a position
  1. below the mean by 2 points
    below the mean by 2 times the standard deviation
    above the mean by 2 points

Solution

Z score = -2.

z scores can be negative..
(data - mean) / standard deviation = z score
if it is negative, it means that the data is below the mean.

Here given as -2.

So answer is below the mean by 2 times the standard deviation

 A z-score of z = -2.00 indicates a position below the mean by 2 points below the mean by 2 times the standard deviation above the mean by 2 points above the me
