Have to find the age of a family of 7. I'm told that the youngest child is 6, the oldest is 16 have a set of twins that are 15. The mean is 11 and the mean is 10. I added up all the numbers and got 73. Thought that if I added 4 I got 77 and then could get to the mean, but that doesn't answer the question. Help
