Answer:
Set A : 45, 65, 66, 67 ,68, 68, 69, 70, 70
Median = 68
Set B : 40, 41, 43, 45, 46, 47, 48, 49, 49
Medain = 46
When 45 is removed from both
Set A : 65, 66, 67 ,68, 68, 69, 70, 70
Median = 68
Set B : 40, 41, 43, 46, 47, 48, 49, 49
Medain = 46.5
Set A : 45, 65, 66, 67 ,68, 68, 69, 70, 70
Mean = 65.33
Set B : 40, 41, 43, 45, 46, 47, 48, 49, 49
Mean = 45.33
when 45 is removed from both
Set A : 65, 66, 67 ,68, 68, 69, 70, 70
Mean = 67.875
Set B : 40, 41, 43, 46, 47, 48, 49, 49
Mean = 45.38
The difference between median of A and B decreases because the median of set B increases.
The difference between mean of A and B increases because the mean of set A increases.
