We asked 15 students at the University of Manitoba, "How many songs are on your iTunes playlist?" The results are shown in the table below:
4141 4760 4413 3420 3400 4978 4406 4298 4066 3896 4678 5100 4916 3631 6018
(a) Find the five-number summary for this dataset (do not use JMP, it calculates the quartiles differently).
(b) If we were to construct a modified (outlier) boxplot of this dataset, an observation would be labeled an outlier if it was less than or greater than .
