Answers
Group A:
A. Mean = Sum of given numbers / count of number
= X1+X2+---------+Xn /n
        = (13+12+11+10+10+09+09+08+07+07)/10
        = 96/10
        = 9.6
B. Here we have the count of numbers is 10 which is even so we take the middle values average
The medina position is in between the 5th term and 6th term.
C.
First we need to make the values in ascending order
07, 07, 08, 09, 09, 10, 10, 11, 12, 13
Median = 5th term + 6th term /2
    = 09+10/2
    = 19/2 = 9.5
