Question

there are ten bird baths in a park. on the first day of spring, the bird baths are filled. several weeks later, the overall change in the water level is found. the results are shown in the table. what is the range of the data?
changes in amount of water (gallons)
1.1 1.4 -2.2 1.5 2.2 -2.3 -0.2 -1.5 2.6 0.9
the range in the change of the amount of water is \\(\square\\) gallons.
(type an integer or a decimal.)

Explanation:

Step1: Find the maximum value

Look at the data set: \(1.1, 1.4, -2.2, 1.5, 2.2, -2.3, -0.2, -1.5, 2.6, 0.9\). The maximum value is \(2.6\).

Step2: Find the minimum value

From the same data set, the minimum value is \(-2.3\).

Step3: Calculate the range

The range is calculated as maximum value minus minimum value, so \(2.6 - (-2.3)\).
\(2.6 - (-2.3)=2.6 + 2.3 = 4.9\)

Answer:

\(4.9\)
