Joseph measures the ropes used to tie boats to a dock. He records the lengths of the ropes in feet and then makes a line plot.
A line plot named "Rope Lengths at Dock" shows a number line from 9 to 13 minutes in increments of one half minute. 9 and one half has 1 dot. 10 has 2 dots. 10 and one half has 2 dots. 11 has 3 dots. 11 and one half has 2 dots. 12 has 1 dot.
Joseph concludes that the difference between the longest and shortest lengths is 212
feet.
Marta disagrees and says that there is no difference. Who is correct?

Marta is correct because the line plot does not show the actual lengths of the ropes used to tie boats to a dock, only the frequency of different lengths. The difference between the longest and shortest lengths cannot be determined from the line plot provided.
