A math question can you help?

I have this math problem and I have no idea how to do it.

I cant write it out so I got a link to it.

I filled in all the black spots but I am not sure if I did it right. The problem tells me I need to find the mean, variance, and standard deviation.

Well I can only put answers in the black parts. So the median in this question is not needed to get the answer right.
The system keeps telling me I am wrong for some reason though.
