In this scenario, you have just been hired away from your Macy's linens department buyer position by the Mall of Elbonia (MoE), as the new food court manager. Why? Rumor had it you have just earned your MBA.
One week ago, the MoE conducted convenience interviews with customers in the mall's food court. One hundred interviews were gathered. The results are summarized in the Mall of Elbonia Interview Results file. In this file, you will find the customers listed in rows, with columns containing data on:
- The customer's gender. (If you need this data for your computations in this assessment, use the coding convention: 0 for female, 1 for male.)
- How much time the customer spent in the mall.
- How much money he or she spent on food.
- The customer's rating of the mall's friendliness and attractiveness.
After you have applied the descriptive data measures, you find the mean to be particularly telling. You believe that you can happily tell the food court owners that the average amount mall customers spend on food during a visit has increased. You realize this is a one-sample test of hypothesis situation. A 2011 study previously found that customers spent an average of $18.75 per visit.
