1. The problem asks to find the range of the given set of numbers: 72, 77, 73, 71, 76, 62, 61, 75. 2. The range of a data set is calculated using the formula: $$\text{Range} = \text{Maximum value} - \text{Minimum value}$$ 3. Identify the maximum and minimum values in the set: Maximum value = 77 Minimum value = 61 4. Substitute these values into the formula: $$\text{Range} = 77 - 61$$ 5. Calculate the difference: $$\text{Range} = 16$$ 6. Therefore, the range of the given numbers is 16.
