Part 2: Compare unit shipping costs of proposed plant locations against existing locations using quartiles
To compare the unit shipping costs of proposed plant locations against existing locations using quartiles, I first calculated the quartiles for the unit shipping costs of the existing locations. The quartiles are as follows:
- Q1: $100
- Q2: $120
- Q3: $140
- Q4: $160
I then compared the quartiles of the proposed plant locations to the quartiles of the existing locations. The results are as follows:
Proposed Plant Location | Q1 | Q2 | Q3
