InferenceSolver

A user-friendly expert system that generates $\LaTeX$-styled solutions to statistical inference problems

Overview

InferenceSolver is a knowledge-based system that...

• Asks the user for problem parameters in plain English
• Outputs detailed solutions as a .tex file with explained calculations, reasoning, and interpretation
• Handles the following parameters:
  • [one/two]-sample
  • [proportion/mean]
  • [ $z$ / $t$ ]
  • [confidence interval/significance test]
  • [random/non-random] [balanced/unbalanced] sample
  • [normal/non-normal] population
