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

For this case we must convert from yards to inches. By definition we have to:
1 yard equals 36 inches
Making a rule of three we have:
1 yd ----------> 36 in
5 yd ----------> x
Where "x" represents the number of inches equivalent to 5 yards.
![x = \frac {5 * 36} {1} = 180](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B5%20%2A%2036%7D%20%7B1%7D%20%3D%20180)
Thus, 5 yards represents 180 inches.
Answer:
