Steps (6) and (7): Determine time spans and probability of occurrences. This is done by selecting any two intervals and adding the percentages between them. For example, there is a 62% probability that the crimes are occurring from 1100 to 1600 hours. (Note the percentages listed above for each hour between 1100 and 1600. When added together, we get 12% + 12% + 14% + 12% + 12% = 62%). Following the same process, we can determine that there is a 27% probability that the crimes are occurring between 0700 and 1100 hours.
