Question 1156446: 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 54.36. Random sampling of 25 scores obtained from individuals who were bullied yielded a mean of 71.57 and a standard deviation of 21.85. (Use these numbers only for this question!)
Calculate the 99% confidence interval.
Steps:
As you know, two values will be required to complete the following equation:

_________ ≤ µ ≤ __________
For this question, what is the value that is above or greater than µ?

The half-interval is t0.995, df=24*s/sqrt(n)
=2.797*21.85/5
=12.22
th upper limit is 71.57+12.22=83.79
