A therapist named Dr. Brown specializes in adolescent anxiety and has been collecting information about the frequency of all clients' anxiety symptoms (a higher number means more frequent symptoms) and comparing them using z-scores.

Alex's

z scoreof 1.6 means her frequency of anxiety symptoms are 1.6standard deviationsmore than the mean of all patients.Z-scoreis defined as the relationship between a particular value or data to the mean of all the data present in a normal distribution. When thez-scoreis zero that means the data is equal to the mean.where x=raw data, =mean and = standard deviation

Standard Deviationis a measure of how dispersed a data set is around its mean or central value. Numerically Standard deviation is defined as the square root of the variance of the distribution.standard deviationmeans the data is clustered togetherstandard deviationmeans that the data is spread out over a larger area.In the given problem as the z-score of Alex is given as 1.6, we can infer that the frequency of anxiety symptoms for Alex is 1.6 standard deviations more than the mean data.

Therefore from the above formula
