## anonymous 4 years ago One way to measure the ability to find one’s way in an environment is to ask people to rate themselves on a Sense of Direction scale. In a sample of college students, including yourself, the mean rating of sense of direction is 30, with a standard deviation of 10. If your rating is 20, what is your z-score

$z= \frac{x-\mu}{\sigma}$ $$\mu$$ is the mean (30 in this problem)\) $$\sigma$$ is the standard deviation (10 here) x is 20 in this problem
