The range of a set of data is 15, and the interquartile range of the same set is 12. Which of the following statements is true about the set?
A) The two ranges are close together, so there is probably an outlier in this set
B) The two ranges are close together, so there are probably no outliers in this set
C) The two ranges are far apart, so there is probably an outlier in this set
D) The ranges are far apart, so there are probably no outliers in this set.

I have no idea how to even start to figure this out! Thanks for all the help!
