Question

Mean of 8, 4, 3, 5, 4, 6 is m and median of 0, 3, 2, m, 5 is n.

The value of n is:

Options

• 5

• 4

• 3

• 0

Answer 1

3

Explanation:

Sum of observations = 8 + 4 + 3 + 5 + 4 + 6 = 30

Number of observations = 6

Mean (m) = `30/6`

m = 5

Substitute the value of m into these numbers

0, 3, 2, 5, 5

Arrange the numbers in ascending order:

0, 2, 3, 5, 5

`(n/2 + 1)`

= `(5/2 + 1)`

= `6/2`

= 3rd

Median (n) = 3

The value of n is 3.
