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.

Resources: Microsoft ExcelÂ®, Spicy Wings Case Study, Spicy Wings Data Set (both the case study and data set are attached)
Develop a 700-770-word statistical analysis. (Do not exceed word count of 10%, excluding cover and reference page wording).
Use descriptive statistics to compute a measure of performance John can use to analyze his delivery performance. Find the following for your measures: (Excel data set is attached) Also, please help explain step-by-step instructions on how to obtain those following statistical data as I am not all that familiar with statistical functions on Excel.
- 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 (To use for the 700-770 word statistical analysis):
