Answer:

Step-by-step explanation:

To find the median number of hours spent watching television by the sample of 13 middle-school students, we need to first arrange the data in  order:

4, 5, 7, 9, 9, 10, 12, 12, 12, 14, 14, 20, 20

Since the number of data points is odd (13 in this case), the median is the middle value when the data is arranged in ascending order.

In this case, the middle value is the 7th value, which is 12. Therefore, the median number of hours spent watching television by the sample of middle-school students is 12 hours.
