Use the given degree оf cоnfidence аnd sаmple dаta tо construct a confidence interval for the population proportion p.A survey of 300 union members in New York State reveals that 112 favor the Republican candidate for governor. Construct the 92% confidence interval for the true population proportion of all New York State union members who favor the Republican candidate.

Scenаriо: Yоu аre develоping а simple application for a university library to handle checking out books. A librarian will use this system to process requests from patrons. Your task is to translate the provided UML diagrams into a basic code structure that follows the Model-View-Controller (MVC) pattern. Class Diagram: Sequence Diagram (checkout process): Based only on the diagrams above, write rough pseudo code (a language like Java/Python is acceptable) for the Model, view, and controller components. Your code should clearly separate the responsibilities of the Model, View, and Controller. Only include what you see in the diagrams; you do not have to actually implement the whole logic in each method. You should, however, write a short comment in the methods on what should happen in these methods. Exact task: 1. Identify the Model, View, and Controller classes and write the basic code for them as described above. 2. Inside each method, write a comment on what should be implemented in that method. 3. Explain the purpose of Model/View/Control for this system and mention what should be implemented where. E.g., This is what you are expected to write as pseudo-code class Patron { private String patronId; private String name; private int checkedOutCount; public boolean canCheckout() { // This method would contain the logic to check if the patron's // checkedOutCount is below the library's limit. }}
