### Network Analysis ExerciseThis exercise requires an examination of a network diagram composed of various nodes and paths. We'll address several questions to understand the network's configuration and workflow.**Questions:**a. **How many different paths are there through the network?** b. **What is the number of the last node in the network?** c. **What is the difference in hours taken for the two paths when they connect at node 10?** d. **What is the difference in hours taken for the two paths when they connect at node 12?** e. **What is the expected duration of the entire project?** f. **What is the critical path?** Separate each node with a dash (–). g. **Which is the longest path?** Separate each node with a dash (–). ---### Diagram DescriptionThe provided network diagram consists of a series of nodes connected by paths with associated time values. These nodes range numerically, starting from node 1 and ending at node 12. Each path connecting these nodes is marked with a number representing the time (in hours) required to traverse the path.- **Node 1 connects to Node 2** with a path labeled 4 hours.- **Node 1 connects to Node 5** with a path labeled 10 hours.- **Node 2 connects to Node 4** with a path labeled 9 hours.- **Node 2 connects to Node 5** with a path labeled 8 hours.- **Node 4 connects to Node 7** with a path labeled 5 hours.- **Node 5 connects to Node 8** with a path labeled 7 hours.- **Node 6 connects to Node 9** with a path labeled 4 hours.- **Node 7 connects to Node 10** with a path labeled 2 hours.- **Node 8 connects to Node 10** with a path labeled 2 hours.- **Node 9 connects to Node 11** with a path labeled 6 hours.- **Node 9 connects to Node 12** with a path labeled 5 hours.- **Node 10 connects to Node 12** with a path labeled 3 hours.- **Node 11 connects to Node 12** with a path labeled 6 hours.This setup allows identification of paths, critical paths, and other network-specific queries relevant

Background: Imagine you work for an e-commerce company that specializes in selling fashion apparel and accessories online. The company has been experiencing a steady growth in customer acquisition but has been facing challenges in retaining these customers. The executive team is concerned about the increasing customer churn rate and wants to develop strategies to improve customer retention. Business Problem: The primary business problem is to reduce customer churn and increase customer retention rates. The company wants to understand why customers are leaving and identify areas where they can make data-driven improvements to retain more customers. This is a critical issue because acquiring new customers is often more expensive than retaining existing ones, and loyal customers tend to spend more over time. Business Research Question: What factors are associated with customer retention? Identify the type of research, i.e., exploratory, descriptive, causal. What type of data will…

A unit needs to be processed at either Machine A or Machine B for Station 2 (parallel lines, both lines performing the same operations). The box is then processed at Station 3. After that, the unit needs to be processed at either Machine A, Machine B or Machine C in Station 4 before leaving the production line. The process time of each station/machine is indicated in the flowchart. What is the process cycle time of this system measured in minutes?
