mean = (17 + 43 + 19 + 8 + 26 + 33 + 8) ÷ 7 = 22
(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)
mean = the sum of 23, 19, 26, 17, 21, 24, 22 divided by 7 = 152/7 =21.71

The Answer: Today at 09:19 26/03/12
mean = the sum of 23, 19, 26, 17, 21, 24, 22 divided by 7 = 152/7 =21.71
19+-26 = 19 - 26 = -7
