Scores on a dental anxiety scale range from 0 (no anxiety) to 40 (extreme anxiety). The scores are normally distributed with a mean of 17 and a standard deviation of 4 . Find the z -score for the given score on this dental anxiety scale. 6 \( z_{6}=\square \) (Type an integer or a decimal.)

To find the z-score for a score of 6 on the dental anxiety scale, you can use the formula: \[ z = \frac{(X - \mu)}{\sigma} \] Where: - \( X \) is the score (6 in this case), - \( \mu \) is the mean (17), - \( \sigma \) is the standard deviation (4). Plugging in the values: \[ z = \frac{(6 - 17)}{4} = \frac{-11}{4} = -2.75 \] So, \( z_{6} = -2.75 \). Feeling anxious about those dental visits? You’re not alone! Many people experience dental anxiety, but understanding your feelings and preparing for appointments can ease the stress.
