Hey! So, an outlier is just a number that is in a data set, but is set farther out from the other number.
So, in this case, your outlier would be 34 because it is not clumped together like the other numbers.
40 would not be your answer because it is NOT part of the data set / box-and-whisker-plot.
Notice how 40 is NOT connected to the series of lines within the box-and-whisker-plot. Because of that, it is NOT part of it.
So, once again, 34 is your outlier.
~Hope I helped!~
