Question

Meena Chavan Corp.’s computer chip production process yields DRAM chips with an average life of 1,800 hours and st.d = 100 hours. The tolerance upper and lower specification limits are 2,400 hours and 1,600 hours, respectively. Based on the given information, the process capability ratio, Cp= ____________ (round your response to two decimal places).

Answer 1

The process capability ratio, Cp is 1.33

Step-by-step explanation:

In order to calculate the process capability ratio, Cp we would have to calculate the following formula:

process capability ratio, Cp= (USL - LSL) / 6 x standard deviation

According to the given data we have the following:

USL = 2,400 hours

LSL = 1,600 hours

Standard deviation = 100 hours

Therefore, process capability ratio, Cp= 2,400 - 1,600 / 6 x 100

process capability ratio, Cp= 1.33

The process capability ratio, Cp is 1.33
