Answer:

B.29

Explanation:

IQR stands for the differences between the means or quartiles of the quadrants and sections of the data set instead of the difference between the opposite ends of the numbers of the biggest and least. So Q1 and Q3 would be the medians of both sections, Q1=42 and Q3=71, no subtracting the values of the quartiles from end to beginning, Q3-Q1, it would be getting us 29.

Hope this helps!! The term made no sense to me when I first came upon it, once I searched it up I got the conception lol.
