[u04a3] Statistical Inference 3 Assessment Description
Assessment Context
By successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:

Competency 3: Analyze business decision opportunities using basic inferential statistics.
Determine the null hypothesis and alternative hypothesis for making decisions regarding customer tendencies.
Competency 4: Assess the use of qualitative data to support business decision-making.
Compute the ANOVA values to indicate acceptance or rejection of a null hypothesis regarding customer tendencies.
Competency 5: Integrate data analysis into general business management planning and decision-making.
Compute the appropriate statistical test to determine acceptance or rejection of a null hypothesis.
Competency 6: Communicate in a manner that is professional and consistent with expectations for members of the business professions.
Communicate in a manner that is professional and consistent with expectations for members of the business professions.
Assessment Instructions
For this assessment, you will apply statistical inference to a business decision 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, linked in the Assessment Resources. 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 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)?

Compile your work into one Microsoft Word file, pasting in the tables you have used to make your calculations. Be sure to clearly title your tables, including each row

and column. Highlight the results of your data calculations within the tables.
