The correct Answer is:
To find the inter-quartile range (IQR) given the values of the first quartile (Q1) and the third quartile (Q3), we can follow these steps: ### Step-by-Step Solution: 1. **Identify the given values:** - Q1 = 153 cm - Q3 = 155 cm 2. **Use the formula for the inter-quartile range:** \[ \text{IQR} = Q3 - Q1 \] 3. **Substitute the values into the formula:** \[ \text{IQR} = 155 \, \text{cm} - 153 \, \text{cm} \] 4. **Perform the subtraction:** \[ \text{IQR} = 2 \, \text{cm} \] 5. **Final answer:** The inter-quartile range is 2 cm.
