Answer:

Mean = 136.2

Median = 105

Step-by-step explanation:

Mean = Sum of numbers    

           Amount of numbers    =0+0+0+8+30+90+120+138+240+240+300+420 = 1586 = 132.16≈ 136.2

                              12                                                   12

Median = odd(the middle number)

             = even(sum of the two middle numbers)

The numbers must be in order.

0, 0, 0, 8, 30, 90, 120, 138, 240, 240, 300, 420

Here the middle number is 90 and 120. So:

Median = 90 + 120 = 210 = 105

                     2             2
