A few automobile accidents happen at different high-risk intersections in Titan region in spite of traffic lights. Traffic Department claims that modification in type of light will decrease these accidents. Commissioners of region have agreed to a proposed experiment. 8 intersections were selected at random, and lights at those intersections were customized. Figures of accidents in a six-month period before and after modifications are given below:

                                                         Number of Accidents
                                                A      B      C      D     E      F       G      H
Before modification                  5      7      6      4      8     9       8      10
After modification                     3      7      7      0     4      6       8       2

At.01 significance level is it sensible to conclude that modification decreased the number of traffic accidents?
