1) Process data from a refrigeration machine at supplier Psy, Inc. shows an average temperature of 25.00 degrees Fahrenheit and a standard deviation of 0.65 degrees Fahrenheit. The specifications from customer Taylor Swift are 25.00 3.25 degrees Fahrenheit, so Lower Specification Limit of 21.75 degrees Fahrenheit and Upper Specification Limit of 28.25 degrees Fahrenheit. Indicate, showing your calculations, what is the Process Capability Ratio (Cp). Please round your final answer to 2 places after the decimal.

2) Same information as previous problem, indicated by quotation marks:

3) The BoA Pizza shop collects data on the number of errors (also known as defects) in pizza orders. The errors are not defined beforehand, and can include a wide variety of issues such as incorrect toppings, incorrect address, discount coupon not applied, special seasoning packet missing, etc.... The data provided below (and provided in an Excel file) gives the number (or count) of errors noted in samples of 100 orders each taken daily for 12 days. Shop owner, Cassidy DeCosta, has requested your help for her/him/them to get started on creating a control chart to track the process. Please name the appropriate control chart that must be used based on this data. Indicate, showing your calculations or describing how you calculated it (there is no option for you to upload a spreadsheet), what is the value of the center line (only) for the appropriate control chart. (Cassidy can complete the rest of the calculations for the chart). Please round your final answer to 2 places after the decimal.
