📌 Project Overview

This project analyzes a medical insurance dataset (from Kaggle) using Java only.
We cannot use Python libraries such as NumPy, Pandas, or Matplotlib — only Java Collections and the standard library.

The program provides:

• Reading & storing the first N records of the dataset into a custom InsuranceRecord object.
• Summary statistics (count, mean, std dev, min, percentiles, max) for numerical attributes.
• Horizontal & vertical text-based histograms.
• Hypothesis checks (fairness by region, smokers vs non-smokers, age vs charges, etc.).
• Simple linear regression & Pearson correlation coefficient for charges vs BMI, children, and region.
• Unit tests (AAA pattern) and Continuous Integration via GitHub Actions.
