Answer #1
Given Data
66.8, 81.8, 87.6, 114.5, 128.4, 102.5, 94.7, 121.8
n = 8
Mean = 
Mean = 798.1 / 8 = 99.76
Mean = 99.76
Option A is Correct
The mean exam time is 99.76
Median :
Arrange in ascending order
66.8, 81.8 87.6 94.7 102.5 114.5 121.8 128.4
Median = 
The median exam time is 98.6
Option A is correct
Mode :
Mode mean repeated number
from the data there is no repeated number
Hence Option B is correct
The Mode Does Not exist
