# Question: Estimate process capability using the x and R charts for

Estimate process capability using the x and R charts for the power supply voltage data in Exercise 6.8 (note that early printings of the 7th edition indicate Exercise 6.2). If specifications are at 350 ± 50 V, calculate Cp, Cpk, and Cpkm. Interpret these capability ratios.
