Using the data from the set included, what is the minimum number of 4's that must be added to make 6 an outlier?
Data Values:-3,-1,1,3,4,5,6,7,9
Frequency: 34,6,12,4,7+x,1,20,3,12
Cumulative Frequency: 34,40,52,56,63+x, 64+x,84+x,87+x,99+x
This is not for homework, it is for an exam review and I am really confused on this one concept.
