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 <=
