Question 1179347
**1. Calculate the Range:**

* **Minimum Value:** 2.34
* **Maximum Value:** 4.10
* **Range:** Maximum - Minimum = 4.10 - 2.34 = 1.76

**2. Determine the Class Width:**

* **Number of Classes:** 10
* **Approximate Class Width:** Range / Number of Classes = 1.76 / 10 = 0.176

**3. Find a "Nice" Class Width:**

* Since the approximate class width is 0.176, we want to choose a "nice" class width that is easy to work with. Common choices include multiples of 0.1, 0.2, 0.25, 0.5, or 1.
* In this case, 0.2 is the most appropriate and "nice" class width.
* If we use 0.2 as the class width, the actual number of classes will be close to 10.

**Answers:**

* The range of the data set is 1.76.
* The nicest class width for 10 classes is 0.2.
