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. Suppose you want to calculate the 99% confidence interval. What is the new critical value you will use for this calculation? ±1.645 ±2.064 ±2.756 ±2.797 6.74
