The tensile strength of an alloy has double specification, Ask an Expert

Statistics

The tensile strength of an alloy has double specification limits. If the process average tensile strength is below 800 kg/cm² or above 1200 kg/cm², it is desired to accept such lots with a probability of 0.08. For lots with a process average of 1000 kg/cm², it is desired that the probability of acceptance be 0.96.

The distribution of tensile strength is normal, with a standard deviation of 80 kg/cm². Find the variable sampling plan and describe its operation.
