While the study found a statistically significant difference in the number of crimes before and after the curfew was instated, the actual decrease in the average number of monthly crimes is quite small (only 1.2 crimes). Additionally, the curfew has reduced city revenue and citizens are not happy with it. Therefore, the researchers should most likely recommend that the curfew be discontinued. Extending the study for one more year may not significantly change the results, and changing the curfew time may not be necessary if the recommendation is to discontinue the curfew altogether.
