What is the RPI index? How can the defective product rate of a production process be determined by using the RPI index? The average distribution range of 2 samples consisting of 4 units is R = 10.8 mm. The tolerance limit is plus – minus 10 mm. Calculate the RPI and evaluate if it will reject. What happens to the reject situation if the tolerance limit is plus-minus 20 mm?

The thickness of a part is to have an upper specification of 0.925 and a lower specification of 0.870 mm. The average of the process is currently 0.917 with a standard deviation of 0.005. Determine the percentage of product above 0.90 mm.
A process has a process capability ratio, C, =1.38, At some time the process seems to have a mean shifted left of the center. The process capability index,Cpk, is found to be 0.78, and the mean is left-shifted, that is the current mean is mess than the mean of the control chart. Determine the Z (UTL) with respect to the current left-shifted mean.

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
