Question

Mean and mode of first 10 composite number

Answer 1

First 10 composite numbers are :
4, 6, 8, 9, 10, 12, 14, 15, 16, 18.

Mean = Sum of all observations ÷ Total no: of observations.
Sum of all observations = 4 + 6 + 8 + 9 + 1 0 +12 + 1 4 +15+ 16 + 18 = 112

Total no : of observations : 10

Mean = 112 / 10
= 11.2

Mode is a no: which occurs frequently in a given set of no:s.
As every no: occurs only once , there is no mode.
