Mean of original dataset = (0+10+15+4+70+15+18+20+6+8+10+12+15+18+20+2+35+40+10) / 19 = 249 / 19 ≈ 13.1

Removing the value 70 from the dataset:
New dataset = {0,10,15,4,15,18,20,6,8,10,12,15,18,20,2,35,40,10}

Mean of new dataset = (0+10+15+4+15+18+20+6+8+10+12+15+18+20+2+35+40+10) / 18 = 248 / 18 ≈ 13.8

Therefore, the mean of the original dataset is approximately 13.1 and the mean of the new dataset after removing the value 70 is approximately 13.8.
