Answer 1

Answer:

Concept: Caclulating Standard Variables

1. We have a five number summary which is more than enough information to calculate our mean.
2. The mean is the sum of all the numbers divided by the nth number of numbers.
3. Note that we can only find a rough estimation not the EXACT value
4. We do (min +max + 2(Q1+median+Q3))/8
5. Now let's plug in our values!
6. (0+85.3+2(8.4+17.4+30.9))/8
7. Which gives us option B
