1. Peterson et al. [2001} compared allmale gangs and allfemale gangs to examine the extent to which each participates in gang ghts. The 3? members of allmale gangs self reported participating in ghts an average of 3.9? times in the past 12 months: with a standard deviation of 4.08. The 13 members of allfemale gangs selfreported participating in ghts an average of 2.513 times in the past 12 months, with a standard deviation of4.3 l . a. Construct 9D% condence interval for these two means. {You will construct 2 condence intervals) (I'D points) h. Construct a 95% condence interval for these two means. [You will construct 2 condence mm points) c. Compare and contrast the 913% and 95% condence interval for the allmale gang- Explain whyr one interval is larger. {5 points)
