### Analysis of Delivery Times for Two Companies

#### Data Used to Construct the Histograms:
The following data represent the number of days required to fill orders for Company A and Company B:

|         |          A          |          B          |
|---------|---------------------|---------------------|
| Days    |   13  10  11  10  11  13   12  12  13  12 |   8  12  15  7  10  13  12  7  15  14 |

#### Histograms:

**Histogram for Company A:**
The histogram displays the relative frequency of delivery times for Company A.

- **X-Axis (Number of Working Days):**
  - Range: 7 to 13 days
- **Y-Axis (Relative Frequency):** 
  - Scale: 0 to 1

The bars show:
- 1 day is between 7 and 8 working days.
- 3 days are between 9 and 10 working days.
- 2 days are between 10 and 11 working days.
- 3 days are between 11 and 12 working days.
- 1 day is between 12 and 13 working days.

**Histogram for Company B:**
The histogram displays the relative frequency of delivery times for Company B.

- **X-Axis (Number of Working Days):**
  - Range: 5 to 17 days
- **Y-Axis (Relative Frequency):** 
  - Scale: 0 to 1

The bars show:
- 1 day is between 5 and 6 working days.
- 1 day is between 6 and 7 working days.
- 2 days are between 7 and 8 working days.
- 1 day is between 9 and 10 working days.
- 2 days are between 11 and 12 working days.
- 2 days are between 13 and 14 working days.
- 1 day is between 15 and 16 working days.

#### Analysis:
Use the range and standard deviation to support the observation that Company A provides more consistent and reliable delivery times.

#### Calculations:
Compute the range and standard deviation of the number of days required to fill orders for Company A. (Round your answers to two decimal places.)

- **Range:** __________ days
- **Standard Deviation:**
