Tony works in a factory that produces 1,000 computers each day. When 50 computers were sampled, it found that 7 were defective. Estimate how many computers are made each day.
We can set up a proportion to solve for the estimated number of computers made each day:
defective computers / total sampled computers = defective computers per day / total computers made per day
Using the numbers given in the problem:
7/50 = x/1000
Solving for x:
x = (7/50) * 1000
x = 140
Therefore, we can estimate that about 140 computers are made each day.
