Case Scenario:
Congratulations. You have just inherited your uncle's business, which is a clothing store. Although the
business was successful, your uncle was a "seat of the pants" type of businessman. There was never any
sales analysis conducted concerning, c.g. determining the effectiveness of promotional policies. You
intend to analyze past sales data to gain insight into the business operations.
The following data in this file corresponds to a random sample of 100 sales transactions that took place
over the previous year. Because all transactions took place during the previous year and all transactions
took place on Saturdays, on non-holiday weekends, you are confident that seasonal and cyclical effects
are absent from the data.
