A tree diagram is a tool used to break down broad categories into finer levels of detail. It is particularly useful for:

Hierarchical Decomposition: Breaking down complex ideas or processes into manageable sub-components.

Problem Solving: Identifying root causes and exploring solutions systematically.

Project Planning: Defining tasks and sub-tasks in a structured manner.

The tree diagram starts with a single node and branches out into multiple nodes, each representing a more detailed aspect of the main topic.

Measuring Test Effectiveness: This involves comparing the number of defects found during testing phases to those found after release.

Importance of Test Effectiveness: It provides insight into how well the testing process is identifying defects before the product reaches the customer.

Impact on Quality: High test effectiveness means most defects are caught during testing, leading to higher quality products and fewer post-release issues.

Portability refers to the ease with which software can be transferred from one environment to another. It is a critical factor in a software product's adaptability as it determines how well the software can function across different platforms, operating systems, or hardware configurations. High portability ensures that the software can be easily adapted to new environments without significant modification, thereby extending its usability and market reach. Reference:

In a concurrent development environment, when a problem is identified in an earlier version (Version 1) that originated in a later version (Version 2), the appropriate action involves managing the code versions effectively. Branching the Version 2 codeline is the most appropriate first step because:

Isolation of Changes: Branching allows for the isolation of the problematic code in Version 2, enabling targeted fixes without affecting ongoing development in other versions.

Concurrent Development: This approach supports concurrent development activities, allowing different teams to work on fixing the issue in Version 2 while continuing development on other versions.

The class intervals 11.5-13.5, 13.5-15.5, 15.5-17.5, and 17.5-19.5 are appropriate for representing the given data set in a histogram. These intervals cover the entire range of the data, ensuring each data point falls within a specific interval, and they are consistent in width, which is crucial for accurate histogram representation.
