Modes : The highest frequency is 12 so, 2 modes.

Mean : Frequency x the number of the frequency and divide it with the total number of the frequency

8,8,9,10,10,11,12,12

The number of frequency | frequency
     8                                       2
     9                                       1
     10                                     2
     11                                     1
      12                                    2


8(2) + 9(1) + 10(2) + 11(1) + 12(2) and divide it by 8+9+10+11+12
Then, you'll get the answer for mean.
