Modified Box Plot Help + Simple Standard Deviation

Hey guys

so i have 3 box plot diagrams given to me:

and i have to answer a few questions on it, without knowing what the actual raw data is:

**1) Which one of the 3 distributions is most likely to have a mean that is greater than the median?**

(my guess is C because the Interquartile Range is the biggest amongst the 3)

2) Which one has the smallest maximumn?

(my guess is A because B has outliers and C looks alot bigger)

3) Which one has the smallest value of Q3?

(my guess is A)

i just want someone to confirm if i'm right on these, thanks.

for Standard Deviation:

Consider a sample of 3 observations, with a standard deviation of s =2. If the smallest two observations are 10 and 12, what is the value of the third observation?

is 14 right? because it says 10 and 12 are the lesser of the 3 observations
