Find the corresponding critical z-value(s) for Type 1 error rate (alpha) of a=0.05

Below are anxiety scores for people who are taking an anxiolytic (anti-anxiety medication). These scores were taken from a random sample of 16 people. In the general population, anxiety scores are normally distributed with a mean (1) of 25 and a standard deviation (0) of 3. You hypothesize that this sample is not representative of the general population. Specifically, you hypothesize that these people form a distinct sub-population, with specifically LOWER anxiety, relative to the general population. That is, if they have higher anxiety, that would be treated the same as having the same amount of anxiety.
