Answer:
465.5
Step-by-step explanation:
If you plug in the numbers into the formula.
base 1= 15
base 2= 34
height= 19
18,38,38,40,44,44,44,46,48....
the mean with the outlier (18) included is : 360/9 = 40
38,38,40,44,44,44,46,48
the mean with the outlier (18) excluded is : (360 - 18) / 9 = 342/9 = 38
so when the outlier is removed, the mean is 2 points less
