which number is closest to the third quartile?

Explanation:

Step1: Recall third - quartile definition

The third quartile ($Q_3$) is the value in a data - set such that 75% of the data lies below it. In a box - and - whisker plot, the right - hand edge of the box represents the third quartile.

Step2: Analyze the given options

Looking at the options 2, 23, and 10, we assume that based on the box - and - whisker plot (even though the plot is not fully clear in terms of scale details), if we consider typical values for quartiles, a value of 2 is too small, and 10 is also likely too small. A value of 23 is more likely to be close to the third quartile as it is the largest among the given options and third quartiles are usually larger values in a data - set.

Answer:

23
