Assessment 7
Use the Mall Time Interview Results file, linked in the
Resources under the Required Resources heading, to complete the calculations
for this scenario.
Practical Application Scenario
As the food court manager at the Mall of Elbonia, you want
to determine how much time customers spend at the mall at different times of
the week (for example: midweek, day; midweek, evening; weekend, day; weekend,
evening). Last week, the mall survey staff administered a random survey to mall
visitors by selecting customers as they were leaving the mall. One of the
questions asked was how much time the customer had spent in the mall on that
day.
The findings from this study are provided in the Mall Time
Interview Results file. In this file, Columns A through D show the time spent
by the customers interviewed, according to the weekday and time of day when the
interviews occurred.
Is there any statistically significant difference (at alpha
= .05) in the average amount of time people spent in the mall, based on the
weekday and time? To determine the answer to that question, you need to
complete the following:
Identify the null and alternative hypotheses you should form
for this test. State each as a written explanation and as a math equation.
Identify the appropriate statistical test you should use to
accept or reject the null hypothesis.
Calculate the appropriate ANOVA values to accept or reject
your null and alternative hypotheses.
What should you tell the operators of the Mall of Elbonia’s
food court stores (in terms of the mall’s high-traffic times and customer
tendencies)? Summarize your statistical analysis in a report for management.
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.
