Questions: A scientist recorded the number of geese found in a park on various days of the week. The data are shown below. 6,9,2,12,3,5,9 What is the range of these data? A. 2 B. 10 C. 12 D. 7

Solution Steps

To find the range of a dataset, subtract the smallest value from the largest value. This will give the difference between the maximum and minimum values in the dataset.

The recorded number of geese in the park on various days is given by the dataset: \[ \{6, 9, 2, 12, 3, 5, 9\} \]

From the dataset, we find:

• Maximum value, \( \text{max} = 12 \)
• Minimum value, \( \text{min} = 2 \)

The range \( R \) is calculated using the formula: \[ R = \text{max} - \text{min} = 12 - 2 = 10 \]
