One hundred customers at the Mall of Elbonia (MoE) were given a brief interview as they concluded their shopping trips. Examine the resulting data in the Mall of Elbonia Interview Results file. For each customer (by row), the spreadsheet contains data on: The customer's gender. How long the customer spent in the mall. How much he or she spent on food and clothing purchases. The customer's rating of the mall's friendliness and attractiveness. MoE's concessions manager believes the average amount that mall customers spend on food during a visit has increased over the historical average of $18.75, due to the opening of some new upscale restaurants in the mall. Use the data in the file to test his hypothesis. (Mean results of food purchased is $20 from the file) What is the null hypothesis? Would you reject it at alpha = .05?
