Answer 2

Answer: 21

Step-by-step explanation:

• Inter-Quartile range is defined as the mean between the lowest observation and the highest observation.
• Here the data given is 17, 18, 18, 19, 20, 21, 21, 23, 25.
• The lowest observation given is 17.
• And the highest observation given is 25.
• So, the Inter-Quartile range is =$\frac{17+25}{2}$

                                                          =$\frac{42}{2}$

                                                          =21

• Hence, the required answer is 21.
