Problem:
Crawford Pharmaceuticals has developed a new drug, Vaxidene, which is administered in the form of a pill. The target amount for a single dose is 100 mg. Patients can receive as little as 98.5mg or as much as 102mg without experiencing ill effects. Because of liability issues, Crawford has determined that it is imperative that the patient receives as close to the target dose as possible. At present, the process mean is 100mg and the standard deviation is 0.4mg
Required:
Question 1) What is the process capability index for Vaxidene? Is the acceptable? Explain.
Question 2) What standard deviation is necessary for a process capability index value of 2? Solve the given numerical problem and illustrate step by step calculation.
