1-A psychologist is interested in knowing whether adults who were bullied as children differ from the general population in terms of
their empathy for others. On a questionnaire designed to measure empathy, the mean score for the general population is 30.6.
Random sampling of 25 scores obtained from individuals who were bullied yielded a mean of 39.5 and a standard deviation of
6.6.
The appropriate statistical procedure for this example would be a
A- z-test
B-t-test
