Case Study 2:

Hanna is required to relocate from Brisbane (where she currently resides) to Perth. Hanna has been actively looking for a house to rent. She has managed to acquire a list of 22 houses that are currently listed for rent in six suburbs contained in file named Residential_Real_Estate. Her friend has told her that, her two preferred suburbs are among the most expensive suburbs to rent. However, Hanna is not convinced.
