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 48.82. Random sampling of 58 scores obtained from individuals who were bullied yielded a mean of 40.03 and a standard deviation of 14.32. (Use these numbers only for this question!)
What is the z-value or t-value you obtained (your test statistic)? (numeric value only, including negative sign if required)
my answer i got was -4.67 is this correct? Fingers crossed lol
