Curbing street gang gun violence. Refer to the Journal of Quantitative Criminology (Mar. 2014) study of street gun violence in Boston, Exercise 2.18 (p. 41). Recall that over a 5-year period (2006–2010), 80 shootings involving a Boston street gang were sampled and analyzed. Of these, 37 occurred in 2006, 30 in 2007, 4 in 2008, 5 in 2009, and 4 in 2010. A program designed to reduce street gang violence was implemented at the end of 2007. If the program is effective, then researchers believe that the percentage of all gang shootings over the 5-year period will break down as follows: 40% in 2006, 40% in 2007, 10% in 2008, 5% in 2009, and 5% in 2010. Give your opinion on the effectiveness of the program.
