A logistics company is experiencing problems with delays in delivering goods to customers. Management wants to use Pareto analysis to identify the main causes of delivery delays and determine the most effective corrective actions. Customer complaint data for the last six months shows various reasons for delivery delays. The data consists of several categories of problems and their frequency:

1. Delivery delays due to scheduling errors: 120 complaints

2. Delivery delays due to inaccurate collection of goods: 90 complaints

3. Delay in Delivery due to Bad Weather Conditions: 60 complaints

4. Delays in Delivery due to Road Obstacles: 40 complaints

5. Delay in Delivery due to Vehicle Failure: 30 complaints

Thank you.
