I would like these rates broken down by credit history category, employment status, and for the middle-age group ranging from 40 to 59 years old. Additionally, please include a breakdown by credit amount range, using bins of 2000. Along with this, could you also answer the following question: How do approval rates fluctuate across different credit history categories, and what does this suggest about the role of a customer's credit history in determining their likelihood of loan approval? 

A. Significantly, Significant,
