1. The problem asks: Approximately what percentage of the data values are between 35 and 50 in the given box plot? 2. A box plot divides data into four quartiles: the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum. 3. The box itself represents the interquartile range (IQR), which is the range between Q1 and Q3. 4. In this box plot, the box spans from 35 to 50, so 35 is Q1 and 50 is Q3. 5. By definition, the IQR contains the middle 50% of the data. 6. Therefore, approximately 50% of the data values lie between 35 and 50. Final answer: Approximately 50% of the data values are between 35 and 50.
