53)
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
[tex]Q3=\frac{14+13}{2}=13.5\approx14[/tex]then the answer is B)14
