Suppose a random variable $x$ is best described by a normal distribution with $\mu = 60$ and $\sigma = 16$. Find the $z$-score that corresponds to the value $x = 0$.
A) $3.75$
B) $- 3.75$
C) $- 16$
D) 16

The z-score is calculated as (x - mu) / sigma, where x is the value of the random variable, mu is the mean, and sigma is the standard deviation. In this case, x = 0, mu = 60, and sigma = 16. Plugging these values into the formula, we get (0 - 60) / 16 = -3.75. Therefore, the z-score that corresponds to the value x = 0 is -3.75.
