The heights (in cm ) of 9 students of a class are \[ 148,144,152,155,160,147,150,149,145 \text {. } \] Find the median height.

To find the **median** height of the 9 students, follow these steps: 1. **List the heights:** \[ 148, 144, 152, 155, 160, 147, 150, 149, 145 \] 2. **Sort the heights in ascending order:** \[ 144, 145, 147, 148, 149, 150, 152, 155, 160 \] 3. **Identify the median:** - Since there are **9** data points (an odd number), the median is the **middle** value. - The middle position is the **5th** value in the sorted list. 4. **Median height:** \[ \boxed{149 \text{ cm}} \]
