Answer:
1.01
Step-by-step explanation:
Mean with outliner = (39.55 + 40.51 + 41.01 + 37.76+ 35.32 + 33.28 + 34.38 + 36.48 + 39.87 + 50.32 + 40.59 + 41.71)/12 = 39.23 seconds.
In this case, the outlier comes to be the data: 50.32. If we don't consider that data point, the mean equals:
Mean wihout outliner = (39.55 + 40.51 + 41.01 + 37.76+ 35.32 + 33.28 + 34.38 + 36.48 + 39.87 + 40.59 + 41.71)/11 = 38.22
The difference is: 39.23 - 38.22 = 1.01
