Explanation

Order the observations: 0,0,6,8,10,14. The median is (6 + 8)/2 = 7

To find the median number of work stoppages, we need to arrange the numbers in ascending order. The given numbers are: 6, 0, 10, 14, 8, and 0.

Arranging them in ascending order: 0, 0, 6, 8, 10, 14.

Now, we can determine the median. The median is the middle value in a set of numbers when they are arranged in ascending order. In this case, we have six numbers, so the median will be the average of the two middle numbers.

The middle numbers are 6 and 8. Therefore, the median will be (6 + 8) / 2 = 14 / 2 = 7.

Therefore, the median number of work stoppages is 7.

Among the given answer choices, option A, 7, is the correct answer.
