hello! I need help with this problem. Thank you very much!
Transcribed Image Text:The data in the following were obtained from a digital thickness measuring gauge. The
wall thickness (in inches) of an unidentified part is the data collected. Ten parts were
selected randomly from a production lot. Three operators were selected from those who
nomally use the same digital gauge. Each of the three operators measured the 10 parts
that were randomly ordered. The 10 parts were again randomly ordered and each of the
three operators again measured the parts. Assess this measurement system by assessing
any significant differences in measurements via Operator, by part items, and the
interaction of operator and parts.

What does the significance results in ANOVA mean for this experiment? If operators
factor is significant, what does it mean for the inspection system? If interaction of parts
and operators is significant, what does it imply about the reliability of the inspection
process whose data was collected from? Can the same part be measured by one operator
and have consistent and reproducible result with another operator? Can you identify
which operator is the best measurer? And which operator is least reliable?
