IrinaK [193]

To find the mean just add all of them then divide the result by 8. To find the median put the numbers in order. So 3, 3, 4, 4, 13, 15, 15, 16 then find the middle number, if there is not middle number (which there isn’t) add the two middle numbers (4 and 13) to get 17 then divide 17 by 2 to get 8.5 which is the median

   (6, 0.7)        3*6 - 11 = 7       10y = 10*0.7 = 7  .....Correct

   (8,2.3)          3*8 -11 = 13       10y = 10*2.3 =23   ..... not correct

   (10, 1.9)        3*10 -11 = 19       10y = 10*1.9 = 19   .... correct
