To determine how many standard deviations an enrollment figure of 9000 is from the mean, you need to first calculate the mean and standard deviation of the relevant dataset. Once you have those figures, the formula for finding the number of standard deviations (z-score) is: \( z = \frac{(X - \mu)}{\sigma} \), where \( X \) is the enrollment number (9000), \( \mu \) is the mean, and \( \sigma \) is the standard deviation. Plug in your values and round! When practicing such problems, a common mistake is misidentifying the mean and standard deviation, or forgetting to round properly at the end. Double-check your calculations step-by-step to ensure accuracy and that you're using the correct values!
