10 numbers in the sample. Middle numbers are 10 and 14. Then the median is (10+14)/2=12
18 plus 4, minus 2
The first 10 composites are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18.
2, 4, 6, 8, 10, 12, 14, 16 4, 8, 12, 16 Yes.
2 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 106
Sum = 4+8+8+11+12+14+16 = 73 Number = 7 So mean = 73/7 = 10 3/7 or 10.4258714...
