Step 1: Given Information

The z-score of x= $7$ , if it is $0.133$ standard deviations to the left of the mean?

Step 2: Explanation

By using the $z - s c o r e$ it can be measured by how many standard deviations ( $σ$ ), the value of x will lie below (left) or above (right) the mean ( $μ$ ) of the distribution. Before it is given that the z-score is $0.133$ standard deviations to the left of the mean for x= $7$
