2.6

-0.8

the range in the change of the amount of water is (square) gallons.
(type an integer or a decimal.)

Explanation:

Step1: Identify maximum value

The maximum value in the data set $\{2.2, 0.8, - 2.1,1.6,2.5,1.9,2.4,-1.8,2.6,-0.8\}$ is $2.6$.

Step2: Identify minimum value

The minimum value in the data set is $-2.1$.

Step3: Calculate the range

The range is calculated as the difference between the maximum and minimum values. So, range = $2.6-(-2.1)=2.6 + 2.1=4.7$.

Answer:

$4.7$
