Purpose of Assignment

The purpose of this assignment is to develop students’ abilities to combine the knowledge of descriptive statistics covered in Weeks 1 and 2 and one-sample hypothesis testing to make managerial decisions. In this assignment, students will develop the ability to use statistical analysis and verify whether or not a claim is valid before advertising it.

Assignment Steps

Resources: Microsoft ExcelÂ®, Spicy Wings Case Study, Spicy Wings Data Set

Develop a ~700-word statistical analysis.

Use descriptive statistics to compute a measure of performance John can use to analyze his delivery performance. Find the following for your measures:

• Mean
• Standard deviation
• Sample size
• Five-number summary on the total time

Conduct a formal hypothesis testing to help John decide whether to offer the delivery guarantee or not.

Estimate the probability of an order taking longer than 30 minutes.

Make a recommendation in a short narrative including the following:

• Based on the sampled data, should John offer the guarantee?
• What percent of the Saturday deliveries would result in a customer receiving a free order?
• What recommendations might help John improve his Saturday delivery times?

Format your assignment consistent with managerial report.

Note: pay special attention to your reporting, even of an excel sheet. Treat it as a report you are submitting to a coleague or supervisor who is infinitely ignorant and infinitly intelligent. Do not let the reader “pick and choose” the relevant parts. Include only what is relevant, in a crystal clear fashion.
