**Frequency Distribution of Fast-Food Drive-Thru Service Times**

The table below represents the frequency distribution of service times, in seconds, for a fast-food drive-thru at a specific location on a given day.

| Time (seconds) | Frequency |
|----------------|-----------|
| 65 - 95.4      | 1         |
| 95.5 - 125.9   | 6         |
| 126 - 156.4    | 10        |
| 156.5 - 186.9  | 28        |
| 187 - 217.4    | 37        |
| 217.5 - 247.9  | 18        |
| 248 - 278.4    | 5         |

**Tasks:**

A. Identify the type of distribution.

B. Calculate the mean and the standard deviation of the drive-thru service times.

---

The frequency table shows the number of occurrences (frequency) for each range of service time (in seconds). With the given data, one can analyze the distribution pattern of service times and perform statistical calculations to understand the overall performance.
