Assessment 4
Use the Mall of Elbonia Interview Results file, linked in
the Resources under the Required Resources heading, and data analysis software
to complete the scenario for this assessment.
You may also use the Hypothesis Tester – Single Sample file
to test your hypothesis; refer to the Hypothesis Tester – An Introduction media
piece (linked in the Resources) to review the process for computing this
equation.
Practical Application Scenario
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.
Directions
Use the data in the Mall of Elbonia Interview Results file
and the process outlined below to confirm that the average amount mall
customers spend on food during a visit to your mall has increased. Use an alpha
of .05.
Determine the null hypothesis via the appropriate math
equation, and write a brief explanation.
Determine the alternative hypothesis via the appropriate
math equation, and write a brief explanation.
Solve the equation to determine whether to accept or reject
the null hypothesis.
Determine whether the p-value indicates acceptance or
rejection of the null. Use alpha = .05.
Next, address the following:
Report the rejection or acceptance of the null, in terms of
the scenario results.
Write a three-sentence paragraph that details:
Why you can be statistically confident that the average
amount a food court’s customer spends has increased, decreased, or remained the
same.
What would happen if alpha was .01 or .10.
Recommend actions to the food court owners based on your
findings.
Additional Requirements
Compile your work and report in a 1–2 page Microsoft Word
file:
Paste in the tables you used to make your calculations.
Clearly title your tables, including each row and column.
Highlight the results of your data calculations within each
table.
