Question

Meena Chavan​ Corp.'s computer chip production process yields DRAM chips with an average life of 1,600 hours and sigma ​= 80 hours. The tolerance upper and lower specification limits are 2,200 hours and 1,500 ​hours, respectively. Based on the given​ information, the process capability​ ratio, Cp ​= ____ ​(round your response to two decimal​ places).

Answer 1

Answer:

1.46

Explanation:

The computation of the process capability​ ratio is shown below:

= (Upper specification limits - lower specification limits) ÷ (6 × standard deviation)

= (2,200 hours - 1,500 hours) ÷ (6 × 80 hours)

= 700 hours ÷ 480 hours

= 1.46

Simply we take the difference of specified limited and then divide it by the standard deviation by multiplying it by 6 so that the correct ratio can come

All other information which is given is not relevant. Hence, ignored it
