Answer:
17
Explanation:
The Interquartile range is the difference between the Quartile 1 and 3. Those quartiles are the median of the left and right side.
Ex: 1, 2, 3, 4, 5
Median = 3, so quartile 1 = median of left side of 3 and quartile 3 = median of right side of 3
First we should organize the data from least to greatest.
38 < 45 < 47 < 50 < 55 < 58 < 60 < 64 < 70 < 71
The median is 56.5.
Quartile 1 = 47
Quartile 3 = 64
64-47 = 17
Hope this helps!
