In a recent survey, 8 people were each asked the number of times they have been on an airplane. Here is a list of the responses. \[ 9,21,7,11,13,21,5,14 \] Find the range of the data set.

To find the range of a data set, we follow these steps: 1. **Identify the maximum and minimum values** in the data set. 2. **Calculate the range** using the formula: \[ \text{Range} = \text{Maximum} - \text{Minimum} \] Now, let's apply these steps to the given data set: The responses are: \[ 9, 21, 7, 11, 13, 21, 5, 14 \] 1. **Find the maximum value**: - The maximum value in the data set is \( 21 \). 2. **Find the minimum value**: - The minimum value in the data set is \( 5 \). Now, we can calculate the range: \[ \text{Range} = 21 - 5 \] Calculating this gives: \[ \text{Range} = 16 \] Thus, the range of the data set is \( 16 \).
