When data is collected for statistical quality control purposes,it is important to record the data,the time the data were collected,the measuring instruments that were used,who collected the data,and any other important information such as lot numbers,machine numbers and the like because ________.

A) it is required by the Federal Trade Commission
B) this type of data can be used to justify our job
C) this will ensure the process is in statistical control
D) the source of quality problems can be traced more easily

Recording the data, time, measuring instruments, who collected the data, and other important information helps trace the source of quality problems more easily. This, in turn, helps in identifying the root cause of the problem and taking appropriate corrective action to address it. It is not required by the Federal Trade Commission, and while it may be useful in justifying one's job, that is not the primary reason for recording this information. Additionally, recording this information may help ensure that the process is in statistical control, but that is not the main reason for doing so.
