Tony works in a factory that produces 1,000 computers each day. When 50 computers were sampled, it was found that 7 were defective. Estimate how many defective computers are made each day. (1 point)

Question

140 computers
7 computers
169 computers
265 computers

Answer 1

Using a proportion, we can set up:

defective computers/total computers = defective computers in sample/total computers in sample

Let x be the number of defective computers made each day. Then:

x/1000 = 7/50

Solving for x, we get:

x = (7/50) * 1000
x = 140

Therefore, the estimate for the number of defective computers made each day is 140. The answer is A) 140 computers.
