it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.
it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer
not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct
the correct answer is c, because 13 is the point in which the plot starts
29 is the correct answer
