Question

A critical dimension of a machined part has specifications 100 + –10. Control chart analysis indicates tht the process is in control with x=104 and R = 9.30. The control charts use samples of size n = 5. If we assume that the characteristic is normally distributed, can the mean be located (by adjusting the tool position) so that all output meets specifications?
