Question

1. make sense and persevere there are ten birdbaths in a park. on the first day of spring, the birdbaths 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 water level (inches) 2.4, 1.4, −2.3, 2.9, 2.3, −1.2, −1.4, −1.8, 2.5, 0.9

Explanation:

Step1: Find the maximum value

The data values are \(2.4, 1.4, -2.3, 2.9, 2.3, -1.2, -1.4, -1.8, 2.5, 0.9\). The maximum value among them is \(2.9\).

Step2: Find the minimum value

The minimum value among the data values is \(-2.3\).

Step3: Calculate the range

The range is calculated as the difference between the maximum and minimum values. So, \( \text{Range} = \text{Maximum} - \text{Minimum} = 2.9 - (-2.3) \)
\( = 2.9 + 2.3 = 5.2 \)

Answer:

The range of the data is \(5.2\) inches.
