Q:
# The gasoline prices in seven states are $1.96, $2.09, $1.79, $1.61, $1.75, 2.11, and $1.84 what is the median gas price and the difference of the first and third quartiles

Accepted Solution

A:

first we must put them in order

1.61, [1.75], 1.79, (1.84), 1.96, [2.09], 2.11

the median (the middle number) = 1.84 <=

the difference of the first and 3rd quartiles (the IQR) =

2.09 - 1.75 = 0.34 <=

1.61, [1.75], 1.79, (1.84), 1.96, [2.09], 2.11

the median (the middle number) = 1.84 <=

the difference of the first and 3rd quartiles (the IQR) =

2.09 - 1.75 = 0.34 <=
