median of

6, 6, 6, 7, 8, 9, 9, 10, 11, 12, 12, 13, 14, 15, 18

n=15

median= X(n+1 )/2

median = x8

median=10

answer

C)10

54)

we are request for the third quartil

since we have 15 values we split this data into 4 datasets each with (n+1 )/2 numbers

6, 6, 6, 7

8, 9, 9, 10,

11, 12, 12, 13,

14, 15, 18

the third quartil can be solve as


Q3=(14+13)/(2)=13.5\approx14

then the answer is B)14
