In a random sample of 50 electrodes, the mean diameter was (0.4 mathrm{~cm}), and the standard deviation

Question:

In a random sample of 50 electrodes, the mean diameter was \(0.4 \mathrm{~cm}\), and the standard deviation was \(0.005 \mathrm{~cm}\).

(a) Between what limits can it be said with \(99 \%\) confidence that at least \(95 \%\) of the diameters of electrodes produced will lie?

(b) Find \(99 \%\) confidence limits for the true mean diameter, and explain the difference between these limits and the tolerance limits found in part (a).
