Answer:
A The mode does not change.
C The mean drops from 185.3 to 172.6.
Step-by-step explanation:
Mean of original data
Mean = (160 + 175 + 166 + 180 + 172 + 178 + 174 + 170 + 178 + 300)/10 = 1853/10 = 185.3
Mean with outlier removed
Mean = (1853 - 300)/9 = 1553/9 = 172.6
The mean drops from 185.3 to 172.6 when the outlier is removed.
Mode
The mode of a data set is the value that occurs most often.
Mode = 178
The mode does not change when you remove the outlier.
