A factory worker conducted a test on a random sample of 150 products. I love the products tested, 2 were found to have defects. Based on this information, how many products in a batch of 3000 are likely to be defective?
so what you would do is 3000 divided by 150 which is 20 then you would multiply 20 by 2 which is 40 so 40 is most likely defective.
Answer:
40 products were likely to be defective.
Step-by-step explanation:
A factory worker conducted a test on a random sample of 150 products out of which 2 were found to be defected.
That means percentage of defective products was = \(\frac{2}{150}\times 100=1.33\)
This concludes that 1.33% products were found to be defective.
Now based on this information we will find defective products in a batch of 3000 products.
Number of defective products = 3000×1.33% = \(\frac{(3000).(1.33)}{100}=40\)
Therefore 40 products were likely to be defective.
