Answer
Explanation:
Step1: Understand box - plot properties
In a box - plot, the box represents the inter - quartile range (IQR). The left edge of the box is the first quartile ($Q_1$), the line inside the box is the median ($Q_2$), and the right edge of the box is the third quartile ($Q_3$). The whiskers extend to the minimum and maximum values within a certain range.
Step2: Identify quartile values
The value of $350$ is the third - quartile ($Q_3$) of the box - plot. By definition, $Q_3$ represents the 75th percentile. This means that 75% of the data values are less than or equal to $Q_3$.
Answer:
75
