A new process is run on consecutive mornings for five days and the yields and other performance data are recorded. When the process goes into full-scale operation, it will be run continuously 24 hours a day. Is it reasonable to consider the yield and performance data from the five morning runs a simple random sample?

Elsa Kim · Answer 1

It will not be a random sample

Step-by-step explanation:

Thinking process:

The process is a scale up process. In the mornings, the process is run and the results are probably tallied and compared against the previous runs. In addition, the averages are taken and compared to other runs. This generally presents a view of how the process is operating.

By definition, a random sample is a sample that is taken randomly.

In this case, the definition will not apply because the process was tested and well-monitored.

Therefore, the accurate data was probably used to scale up the operations to 24 hrs per day.
