Q. Lily checked the available memory on

8

computers in the computer lab. The amounts were:

\newline

1.4\,\text{GB}

,

3.5\,\text{GB}

,

1.4\,\text{GB}

,

5.4\,\text{GB}

,

1.4\,\text{GB}

,

4.3\,\text{GB}

,

3.5\,\text{GB}

,

1.6\,\text{GB}

\newline

What was the range of the amount of memory available?

\newline

\_\_\_\_\_\,\text{GB}

Arrange Data in Ascending Order: Step $1$ : $1.4\,\text{GB}$ , $3.5\,\text{GB}$ , $1.4\,\text{GB}$ , $5.4\,\text{GB}$ , $1.4\,\text{GB}$ , $4.3\,\text{GB}$ , $3.5\,\text{GB}$ , $1.6\,\text{GB}$ $\newline$ Arrange the data points from least to greatest. $\newline$ Data set in ascending order: $1.4\,\text{GB}$ , $1.4\,\text{GB}$ , $1.4\,\text{GB}$ , $1.6\,\text{GB}$ , $3.5\,\text{GB}$ , $3.5\,\text{GB}$ , $4.3\,\text{GB}$ , $5.4\,\text{GB}$
Calculate Range: Step $2$ : $1.4\,\text{GB}$ , $1.4\,\text{GB}$ , $1.4\,\text{GB}$ , $1.6\,\text{GB}$ , $3.5\,\text{GB}$ , $3.5\,\text{GB}$ , $4.3\,\text{GB}$ , $5.4\,\text{GB}$ $\newline$ Calculate the range of the memory amounts. $\newline$ Range = Largest value - Smallest value = $5.4\,\text{GB} - 1.4\,\text{GB} = 4.0\,\text{GB}$
