Its been a while since I did a CI so I am a bit rusty. I had 19 steel pins which all had an actual diameter of .375 in, so mean is known. I measured each pin with both a vernier caliper and micrometer to test the variability of each tool. When I do a 95% CI for the data collected should I use the actual mean .375 or the "sample" mean from my recorded measurements? A colleague of mine used the nominal mean which threw me off, they seemed pretty confident.

thanks

The data is collected from both managers and subordinates, the first one has 3 variables (mediator, IV and DP) and the 2nd has just one (moderator).
