Question A manufacturer of computer chips has a computer hardware company as its largest customer. The computer hardware company requires all of its chips to meet specifications of 1.2 cm. The vice-president of manufacturing, concerned about a possible loss of sales, assigns his production manager the task of ensuring that chips are produced to meet the specification of 1.2 cm. Based on the production run from last month, a 95% confidence interval was computed for the mean length of a computer chip resulting in: 95% confidence interval: (0.9 cm, 1.1 cm) What are the elements that the production manager should consider in determining his company’s ability to produce chips that meet specifications?

Solution

The elements that the production manager should consider in determining his company’s ability to produce chips that meet specifications are:-

1. The manager needs to increase the upper limit and lower limit of the dimension of chip. They need to produce chip between 1.1 cm to 1.3 cm in order to get mean of 1.2.

2. The manager also needs to go through the calibration of meter scale so that the human error can be eliminated.

3. The next sample mean should be taken on daily basis after calibration to reduce the error.
