Answer 1

upper quartile the median of the upper half of the data set; a value which 75% of the data set falls below

Answer 2

i think its 3 cuz 75% is 1/4 and if it was even it would be 12 but its odd so it must be 13 ????????????

Answer 6

if we start with and odd number, them we expect to have

*even #* median *even #*

next we divide the top *even #* into two chunks: A B
they say B has 3, so I would put 3 into A... so 6 above the median.
by definition we must have 6 below the median.
6+1+6 = 13
