what percentage of data points do the two whiskers contain?\n25%\n30%\n50%\n75%

Explanation:

Step1: Recall box - and - whisker plot properties

In a box - and - whisker plot, the box contains the middle 50% of the data. The two whiskers together contain the remaining data.

Step2: Calculate the percentage of data in whiskers

Since the total percentage of data is 100% and the box contains 50% of the data, the percentage of data in the two whiskers is (100 - 50=50%).

Answer:

50%
