The following data set is the age of customers at the ice cream shop: \[ 18,52,42,36,5,31,29,22 \] Find the median.

1. **Order the data from least to greatest:** The ordered data set is: \[ 5,\, 18,\, 22,\, 29,\, 31,\, 36,\, 42,\, 52 \] 2. **Determine the number of observations:** There are \(8\) data points. 3. **Identify the middle two values:** Since the number of observations is even, the median is the average of the \(\frac{n}{2}\)-th and the \(\left(\frac{n}{2}+1\right)\)-th terms. - The \(4\)-th term is \(29\). - The \(5\)-th term is \(31\). 4. **Calculate the median:** \[ \text{Median} = \frac{29 + 31}{2} = \frac{60}{2} = 30 \] The median is \(30\).
