on a 50-point history test the median was 34 and Q1 was 28. one student got a perfect paper and qualified as an outlier under the 1.5 X IQR criterion. what is the largest value Q3 could be?

Answer 1

1.5*IQR=(49-28)
IQR=21/1.5=14
So
Q3=Q1+IQR=42

However, the median and Q1 should be recalculated after the outlier is removed.
