To find out the expected number of defective chips in a year, we can use the concept of proportion.
The proportion of defective chips in the sample can be calculated as (number of defective chips)/(total number of chips in the sample):
Proportion of defective chips = 22/600 = 0.0367
Therefore, we can assume that approximately 3.67% of the chips in the sample are defective.
To find the expected number of defective chips in a year, we can multiply this proportion by the total number of chips manufactured in a year:
Expected number of defective chips = 0.0367 * 36,000 = 1,332.4
Therefore, we can expect approximately 1,332 defective chips out of the 36,000 chips manufactured each year.
In a semiconductor company's quality control test, a machine found that 22 out of a sample of 600 computer chips were defective.
How many of the 36,000 computer chips the company makes each year would you expect to be defective?
