[AI-generated answer — Bot GPT 3.5]

To find the median, we first need to rearrange the list in numerical order:

{0, 7, 8, 8, 10, 11, 14, 15, 17, 17.5, 18, 18, 18, 20, 30}

Since there are 15 numbers in the list, the middle number will be the 8th number in the list.

The 8th number is 17.

Therefore, the median number of hours spent on screens for the kids surveyed is 17 hours.
