Problem 1. 10 parts are measured by three inspectors three times and the measurements are recorded in the following table. (Use a = 0.05) Is there any significant difference between the performance of inspectors? a) b) Based on the data, can we say the part means are the same? c) What can you say about the difference among inspectors when we move from one part to another one?
