Question 1194871
.
The records of a light bulb manufacturer show that, when the manufacturing machinery is working correctly, 
the defect rate (due to imperfections in the material used) is 1%. The manufacturer's control department 
periodically tests samples of the bulbs, and when 1.5% or more are defective, they call repair technicians for service.
The control department is going to take a random sample of 4400 light bulbs. Let  be the proportion of defective 
light bulbs in the sample assuming the machinery is working correctly.
