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.
