The federal government recently granted funds for a special program designed to reduce crime in high-crime areas. A study of the results of the program in high-crime areas of Miami, Florida, are being examined to test the effectiveness of the program. The difference in crimes reported is calculated as (crimes after - crimes before). You want to test whether the crimes reported after is different from those reported before and, thus, the hypotheses are as follows: Null Hypothesis: ?D = 0, Alternative Hypothesis: ?D ? 0. You perform a paired sample t-test and see a p-value of 0.0018. What is the appropriate conclusion?

 

1) The average difference in crimes reported is equal to 0.

2) The average difference in crimes reported is significantly different from 0. There is a significant difference in crimes reported due to the program.

3) The average difference in crimes reported is significantly less than 0. The average number of crimes reported was higher before the program.

4) We did not find enough evidence to say the average difference in crimes reported was not 0. The program does not appear to have been effective.

5) The average difference in crimes reported is significantly larger than 0. The average number of crimes reported was higher after the program.
