Answer:
The standard deviation is 11 points
Step-by-step explanation:
To calculated the z-score of a value x, we use the following equation:

Where m is the mean, s is the standard deviation and z is the z-score.
If we solve this equation for s, we get:

So, replacing z by 2, m by 153 and x by 175, we get:

Therefore, the standard deviation is 11 points
