1. much has been made about the overall intelligence of criminal offenders in general, and violent offenders particular. there is an assumption that violent offenders are inherently less intelligent than non-violent offenders. to test this idea, data were collected from two separate groups of offenders (violent offenders and property offenders). intelligence scores were obtained for every offender in the two samples. 2. submit your solution (step-by-step calculations), and the conclusion here. descriptive statistics appear below: property offenders = average iq = 96, sd = 8.5, n=225 violent offenders = average iq = 88, sd = 7.5, n=200 use t to test the following set of hypotheses at the 95% level of confidence: h_a: violent offenders are less intelligent than property offenders h_o: violent offenders and property offenders do not differ significantly with regard to intelligence scores
