A quality control inspector finds 9 defective units in a sample of 60 cellular phone. At this ratio, how many units can the insp
1 answer:
The inspector can expect to find 450 units in a batch of 3000 phones
Step-by-step explanation:
Given
Total Cellular Phones = S = 60
Defective phones = E = 9
We will calculate the probability of defective forms first
So,
The probability of defective phones in 60 phones is 0.15
Now,
Total phones = 3000
The inspector can expect to find 450 units in a batch of 3000 phones
