Let's solve the problem step-by-step: ### **Step 1: Organize the Data into 5-Minute Intervals** We need to count how many calls were received in each 5-minute interval. The times range from 1:03 to 2:19. We will group times as follows: - 1:00–1:04 - 1:05–1:09 - 1:10–1:14 - ... and so on, up to 2:15–2:19. #### **List of Intervals and Counts** Let's go through the call times and place each call into its respective interval. #### **1:00–1:04** - 1:03 (call 1) **Count: 1** #### **1:05–1:09** - 1:06 (call 2) - 1:09 (call 3) **Count: 2** #### **1:10–1:14** - 1:11 (call 4) - 1:12 (call 5) **Count: 2** #### **1:15–1:19** - 1:17 (call 6) **Count: 1** #### **1:20–1:24** - 1:21 (call 7) **Count: 1** #### **1:25–1:29** - 1:27 (call 8) - 1:28 (call 9) - 1:29 (call 10) **Count: 3** #### **1:30–1:34** - 1:31 (call 11) - 1:36 (call 12) ← next interval **Count: 1** (only 1:31 counts here) #### **1:35–1:39** - 1:36 (call 12) - 1:39 (call 13) **Count: 2** #### **1:40–1:44** - 1:42 (call 14) - 1:43 (call 15) - 1:44 (call 16) **Count: 3** #### **1:45–1:49** - 1:47 (call 17) - 1:48 (call 18) **Count: 2** #### **1:50–1:54** - 1:50 (call 19) - 1:52 (call 20) - 1:53 (call 21) **Count: 3** #### **1:55–1:59** - 1:56 (call 22) - 1:56 (call 23) **Count: 2** #### **2:00–2:04** - 2:00 (call 24) - 2:00 (call 25) - 2:01 (call 26) - 2:02 (call 27) - 2:03 (call 28) - 2:03 (call 29) - 2:04 (call 30) **Count: 7** #### **2:05–2:09** - 2:06 (call 31) - 2:07 (call 32) - 2:08 (call 33) - 2:08 (call 34) **Count: 4** #### **2:10–2:14** - 2:11 (call 35) - 2:12 (call 36) - 2:12 (call 37) - 2:13 (call 38) - 2:14 (call 39) - 2:14 (call 40) **Count: 6** #### **2:15–2:19** - 2:16 (call 41) - 2:19 (call 42) **Count: 2** --- ### **Step 2: Create a Run Chart Table** | Interval (min) | Calls Received | |----------------|---------------| | 1:00–1:04 | 1 | | 1:05–1:09 | 2 | | 1:10–1:14 | 2 | | 1:15–1:19 | 1 | | 1:20–1:24 | 1 | | 1:25–1:29 | 3 | | 1:30–1:34 | 1 | | 1:35–1:39 | 2 | | 1:40–1:44 | 3 | | 1:45–1:49 | 2 | | 1:50–1:54 | 3 | | 1:55–1:59 | 2 | | 2:00–2:04 | 7 | | 2:05–2:09 | 4 | | 2:10–2:14 | 6 | | 2:15–2:19 | 2 | --- ### **Step 3: Interpretation** - The number of calls is relatively low and steady (between 1–3 calls per interval) **before 2:00**. - **After 2:00**, there is a sharp increase: 7 calls in one interval (2:00–2:04), 4 in the next, and 6 in the following interval. - The spike suggests a sudden surge in emergency calls starting at 2:00. This could indicate an incident or event that caused many people to call at the same time. - Three operators on duty may have been overwhelmed during the peak intervals. --- ### **Final Answer** #### **Run Chart Data Table** | Interval (min) | Calls Received | |----------------|---------------| | 1:00–1:04 | 1 | | 1:05–1:09 | 2 | | 1:10–1:14 | 2 | | 1:15–1:19 | 1 | | 1:20–1:24 | 1 | | 1:25–1:29 | 3 | | 1:30–1:34 | 1 | | 1:35–1:39 | 2 | | 1:40–1:44 | 3 | | 1:45–1:49 | 2 | | 1:50–1:54 | 3 | | 1:55–1:59 | 2 | | 2:00–2:04 | 7 | | 2:05–2:09 | 4 | | 2:10–2:14 | 6 | | 2:15–2:19 | 2 | **Conclusion:** There was a major surge in call volume starting at 2:00, likely due to a specific event or emergency. The operators may have been overwhelmed during this time. --- **If you need a run chart (graph), let me know and I can provide that as well!**
