Around what age do children learn that there are customs and rituals associated with death such as funerals, cremation, and cemeteries

I believe the correct answer is: around the age of 9.

At 9 years old, most children begin to understand that death is universal, final, irreversible, a nonfunctional state, and that there are customs and rituals associated with death such as funerals, cremation, and cemeteries. But, even though children reach this level of understanding, they continue to struggle with the idea that death is final.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !
