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 60.03. Random sampling of 25 scores
obtained from individuals who were bullied yielded a mean of 90.5 and a
standard deviation of 16.51.
Calculate the 99% confidence interval.
For this question, what is the value that is below or less than µ?
