A researcher recorded the amount of time, rounded to the nearest second, that it took each of 14 people to complete a certain task. The recorded times are summarized in the boxplot shown. Which of the following statements must be true?

Indicate all such statements.


The scatterplot shows the amount of time, in minutes, that it took a team of two people to mow each of 10 lawns, including a lawn with area 4,100 square feet.
