Answer:
The median amount of time students spent on homework last week was 180 minutes.
Explanation:
The median is the middle value when all data values are placed in order of size.
If there is an even number of elements in the data set, the median is the average of the two middle numbers.
From inspection of the given dot plot, the number of hours the 10 students spent doing homework last week in order of size is:
- 2, 2, 3, 3, 3, 3, 4, 4, 5, 6
The two middle numbers are 3 and 3. Therefore, the average of these two numbers is 3, so the median amount of time students spent on homework last week was 3 hours.
As there are 60 minutes in one hour:
⇒ 3 hours = 3 × 60 minutes = 180 minutes
Therefore, the median amount of time students spent on homework last week was 180 minutes.
