Prog 2

This document serves as the program library write-up for "PROG 2," a software tool designed to calculate the significance of differences (Student's "t") between two groups of heartbeat intervals. Specifically, it analyzes the number of intervals of a particular duration within two larger groups of varying durations, assuming infinite degrees of freedom. The document provides the mathematical formula used for the calculation, defines the variables required, and outlines the usage instructions for loading and running the program on the system.
