Researchers studying a crime prevention program report there was a mean reduction of 1.59 property crimes per month across the neighborhoods included in the sample. To support their conclusion, they report a 95% confidence interval of -0.91 4.09 (i.e., 1.59 2.50) for the mean reduction in property crimes. Do you agree with the researchers' claim that this program was effective? Fully explain why or why not, using the confidence interval result provided and other relevant material covered in the module.
