The middle 50% of fire sizes are found between the first quartile (Q1) and the third quartile (Q3). Given Q1 = 197 acres, and the interquartile range (IQR) = 370 acres, we can find Q3 by adding the IQR to Q1: Q3 = 197 + 370 = 567 acres. Therefore, the middle 50% of fire sizes are found between 197 acres and 567 acres.
