What is the value represented by the letter e on the box plot of the data?
{45, 45, 50, 55, 60, 65, 72, 75, 80, 80, 90}

E represents the maximum.

For future reference, A is the minimum, B is the lower quartile, C is the median, and D is the upper quartile.

EDIT: Just realized that I answered this incorrectly, I'm pretty sure E represents the value of 90, since it is the highest of the values listed, and the maximum is the highest.
