These segments include customers aged 40-59, those with stable employment, and those with good or excellent credit history. The approval rates can be calculated by determining the percentage of favorable decisions within each segment. For the stable employment category, please consider customers who have been employed for 7 years or more, as well as those employed between 4 and 7 years. Regarding the credit history, include customers with a record of 'existing paid', 'no credits/all paid', or 'all paid'. Additionally, could you please answer my question: What is the percentage decrease in the rejection rate of the youngest age group compared to the age group with the second highest rejection rate?
