Answer 2

A. The mean decreases by 3.
B. The mean increases by 2.
C. The mean increases by 3.
D. There are no outliers.

Answer 3

D can immediately be eliminated, because there is clearly an outlier
You know A isn't right either because the outlier is lower than most of the data, so removing it would have to make the average rise
Then with B and C, you'd have to just calculate both means to see

Answer 4

Ok, Thank You!
