Answer:
The median gasoline price is $1.84
The difference of the first and third quartiles in this set of gas prices is $0.34
Step-by-step explanation:
Let's order the seven gasoline prices given, this way:
$1.61, $1.75, $1.79, $1.84, $1.96, $2.09, $2.11
Now, let's cut the list into quarters:
$1.61, $1.75,
$1.79, $1.84, $1.96,
$2.09, $2.11
And the result is:
Quartile 1 (Q1) = $1.75
Quartile 2 (Q2), which is also the Median, = $1.84
Quartile 3 (Q3) = $2.09
The median gasoline price is $1.84
The difference of the first and third quartiles in this set of gas prices is $ 0.34 (2.09 - 1.75)
