The federal government recently granted funds for a special program designed to reduce crime in highcrime areas. A study of the results of the program in highcrime 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 before is less than those reported after and, thus, the hypotheses are as follows: Null Hypothesis: ?_{D} ? 0, Alternative Hypothesis: ?_{D} < 0. You perform a paired sample ttest and see a pvalue of 0.9633. What is the appropriate conclusion?
Question 13 options:









We reject H_{0} if pvalue is less than level of significance.
In this case pvalue is very high i.e. 0.9633. This means we do not reject H_{0} and reject the alternative hypothesis, i.e., the average difference is negative. This means the program does not appear to have been effective. Hence, the answer is
3) We did not find enough evidence to say there was a significantly negative average difference in crimes reported. The program does not appear to have been effective.
