Answer:
D. The mean will increase and the median will remain the same
Step-by-step explanation:
First I’d order them from smallest to largest in the data set:
3, 5, 6, 6, 7, 11
The median here is 6.
Then the mean would be 6.33
Then it says if 3 is removed:
5, 6, 6, 7, 11
So we would know the median is 6
The mean here would be 7
So we can see the mean increases but the median stays the same, therefore the answer is D
