Question

Mean, media, mode of 4,5,7,9,11,12,14,16,18

Answer 1

Explanation:

4,5,7,9,11,12,14,16,18

n = 9

•› Mean

`\bar{x} = (4 + 5 + 7 +9 + 11 + 12 + 14 + 16 + 18)/(9)`

`\bar{x} = (96)/(9)`

`\bar{x} = 10.67`

•› Median

`Me = X_{(n+1)/(2)}`

`Me = X_{(9+1)/(2)}`

`Me = X_{(10)/(2)}`

`Me = X_(5)`

`Me =12`

•› Mode

Mo = 0
