Question

D A product is made of 4 major modules. If any of the 4 modules is defective, the phone becomes defective. Your goal is to have a 93 percent quality for the finished product. Assuming all 4 modules have identical process performance, each module should have Y percent quality to meet your goal. Type in the answer rounded up to 2 places. 03

Answer 1

Quality of finished product = 93% = 0.93

Number of modules = 4

Let the process performance quality of each module be z.

As per question, all four modules have identical process performance.

That means,

z*z*z*z = 0.93

z​​​​​​4 = 0.93

z = (0.93)1/4

z = 0.9820 or 98.20%

Hence process performance quality of each module is 98.20%.
