Jamie checked the available memory on 7 computers in the computer lab. The amounts were:
6 GB6 GB6 GB7 GB5 GB9 GB9 GB
What was the range of the amount of memory available?

GB

Answer 1

To calculate the range of the amounts of memory available, we first need to identify the maximum and minimum values from the data set.

The amounts of memory are:

- 6 GB
- 6 GB
- 6 GB
- 7 GB
- 5 GB
- 9 GB
- 9 GB

1. **Identify the Maximum and Minimum Values:**
- Maximum: 9 GB
- Minimum: 5 GB

2. **Calculate the Range:**
\[
\text{Range} = \text{Maximum} - \text{Minimum}
\]
\[
\text{Range} = 9 \text{ GB} - 5 \text{ GB} = 4 \text{ GB}
\]

The range of the amount of memory available is **4 GB**.
