question
the box plot below represents some data set. what percentage of the data values are greater than 130?

Explanation:

Step1: Recall 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 non - outlier values. Here, assume the box starts at $Q_1$, the line in the box is $Q_2$, and the end of the box is $Q_3$. Since 130 is approximately at the median ($Q_2$) position.

Step2: Use quartile percentages

The median divides the data set into two halves. 50% of the data lies below the median and 50% of the data lies above the median.

Answer:

50%
