Answer
Explanation:
Step1: Recall box - plot properties
In a box - plot, the box represents the inter - quartile range (IQR). The lower quartile ($Q_1$) is the value at the start of the box and the upper quartile ($Q_3$) is the value at the end of the box. The median is the line inside the box. The range from $Q_1$ to $Q_3$ contains 50% of the data. Also, if we consider the lower whisker to $Q_1$ and $Q_3$ to the upper whisker, each part (outside the box but within the whiskers) contains 25% of the data.
Step2: Identify quartile values from box - plot
Assume that 25 is the lower quartile ($Q_1$) and 50 is the upper quartile ($Q_3$).
Step3: Calculate the percentage of data
The percentage of data between $Q_1$ and $Q_3$ is 50%.
Answer:
50
