Concept: Caclulating Standard Variables 
- We have a five number summary which is more than enough information to calculate our mean.
 - The mean is the sum of all the numbers divided by the nth number of numbers.
 - Note that we can only find a rough estimation not the EXACT value 
 - We do (min +max + 2(Q1+median+Q3))/8 
 - Now let's plug in our values!
 - (0+85.3+2(8.4+17.4+30.9))/8 
 - Which gives us option B
