1. For each CardioGood Fitness treadmill product line (see the CardioGoodFitness file), construct two- way contingency tables of gender, education in years, relationship status, and self- rated fitness. (There will be a total of six tables for each treadmill product.)

2. For each table you construct, compute all conditional and marginal probabilities. 

3. Write a report detailing your findings to be presented to the management of CardioGood Fitness.
