The graph below shows the cost of pens based on the number of pens in a pack. what would be the cost of one pen?
a graph is shown with title purchase of pens. the horizontal axis label is number of pens, and the vertical axis label is cost in dollars. points are plotted on the ordered pairs 3, 4.50, and 5, 7.50 and 7, 10.50.
$1.50
$2.30
$6.00
$13.50

the data of the detroit pistons in numerical order from least to greatest is 0.30, 0.37, 0.55, 0.62, 0.69, 0.72, 0.73, 0.75, 0.77, 0.78, 0.80, 0.81, 0.81, 0.83, 0.84, 0.89

the data of the miami heat in numerical order from least to greatest is 0.50, 0.50, 0.56, 0.57, 0.67, 0.72, 0.72, 0.72, 0.75, 0.75, 0.76, 0.81, 0.82, 0.90, 1.00, 1.00

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05

other answer is correct. i had used the radius of the radius somehow. a website:

one set of data has more variation than the other. hope this !
