a child is born to mr.x every year for 7 consecutive years.
Compute the mean of the children's age when;
i- the youngest is 1 year old.
%28%281%2B2%2B3%2B4%2B5%2B6%2B7%29%29%2F7 = 28%2F7 = 4 yrs is the mean
:
ii- the youngest is 8 years old.
%28%288%2B9%2B10%2B11%2B12%2B13%2B14%29%29%2F7 = 77%2F7 = 11 yrs is the mean
