Based on prior knowledge, it is expected that a person's age could play a significant role in determining whether they receive credit or not. Younger individuals, such as those between 18-28 years old, may have less credit history and thus may have a lower likelihood of being approved for credit. On the other hand, individuals between 25-45 years old may have had more time to establish a positive credit history, increasing their chances of receiving credit. Therefore, the dictionary contains typical age values for both classes to capture the relationship between age and credit approval.
