A clinical psychologist is interested in testing whether serial killers are more introverted than the general population. A sample of 9 serial killers serving life sentences was tested and found to have a sample mean introversion score of 41 and standard deviation (s) of 6.8. If the population mean (µ) is 36, are serial killers significantly different from the normal population? What inferential test did you use? Using an alpha level of .05(two-tailed), determine whether the sample was significantly different from population. Report and interpret an effect size.
