[USER (data scientist)]:Hello Tapilot, I require your assistance in analyzing the 'credit_customers' dataset. Could we begin by examining the distribution of age, employment status, and credit history among our customers within this dataset? I would appreciate it if you could provide the mean, median, mode, range, and distribution plots for these variables. Based on the data analysis, could you also answer the following question: What is the second most common employment status among our customers, and how many customers fall under this category?

B. 7 or more years of employment, 253
C. 1 to 4 years of employment, 237
D. 7 or more years of employment, 237
