Answer:
Step-by-step explanation:
The box plot shows all three quartiles, where the first one is 45, the second quartile is 50 and the third quartile is 67 (remember that there are only three quartiles in a dataset).
Now, the interquartile range is defined as the difference between the third and first quartile, which in this case is 67 - 45 = 22.
Therefore, the interquartile range is 22.
