  1. 3 | 7 8 9 ---> 37, 38 , 39
    4 | 1 3 7 ---> 41 , 43 , 47
    5 | 2 4 ---> 52 , 54

    and a. is:

    a. 37, 38, 39, 41, 43, 47, 52, 54

    so I do not think c is right.
    I am not educated enough in this to look at the rest.

    4. C - its a graph
    5. D 35
    6 D - Mean, the outliers are limited
    7 C 6 years
