A Sydney manufacturing company operates on three shifts per day: morning shift, afternoon shift and evening shift. This company installed a new machine in January 2021. The Chief Executive Officer (CEO) of the company has asked the production manager to assess the new machine's performance. The production manager visited several morning shifts and collected a sample of data, including the following: number of parts manufactured per minute (000s), number of times the machine needed to be serviced; number of employees required to staff the machine; and quality of parts manufactured. In February 2021, the production manager wrote a report on the new machine's performance to present to the CEO.

a) Describe the 5 W's and how of the data.

b) Do you feel that the sample collected by the production manager would suffer from any errors? Briefly explain.
