Question
One week ago, the MoE conducted convenience interviews 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. Use the data in the Mall of Elbonia Interview Results file (linked in the Resources under the Required Resources heading) and the process outlined below to be sure that your suspicions are correct, and that the average amount mall customers spend on food during a visit to your mall has increased. Use an alpha of .05. 1.Determine the null hypothesis via the appropriate math equation, and write a brief explanation. 2.Determine the alternative hypothesis via the appropriate math equation, and write a brief explanation. 3.Solve the equation to determine whether to accept or reject the null hypothesis. 4.Determine whether the p-value indicates acceptance or rejection of the null. Use alpha = .05.'
Can you use the hypothesis tester?
