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 at the left - hand side of the box and the upper quartile ($Q_3$) is at the right - hand side of the box. The median is the line inside the box. The whiskers extend to the minimum and maximum values within 1.5 * IQR of the quartiles.
Step2: Identify quartile values from the box - plot
From the box - plot, assume the lower quartile ($Q_1$) is 25 and the upper quartile ($Q_3$) is 50.
Step3: Calculate the percentage
The inter - quartile range contains 50% of the data. So the percentage of the time the mayor received between 25 and 50 emails is 50%.
Answer:
50%
