The Manufaturing Company allows the defect rate of 0.6% on its production line. The defect average for last week was 4 items out of 4,400. What is the difference between the allowed defect rate and the defect average for last week? Please I really don't get this stuff.

Answer 1

To find the number of products allowed with defects:

Multiply: 0.006 * 4,400 = 26.4

What's the difference between the allowable and the actual rate?
