Answer:
The average defective rate = .057
Step-by-step explanation:
Given -
Sample size n = 100
Day - 1 2 3 4 5 6 7 8 9 10
Defectives - 7 6 6 9 5 6 0 8 9 1
The average defective rate is the no of defective in each day for past ten days
The average defective rate = [tex]\frac{\sum no\; of \; effective \; in\; each\; day}{no\; of \; day \times n}[/tex]
= [tex]\frac{7 + 6 + 6 + 9 + 5 + 6 + 0 + 8 + 9 + 1}{10\times 100}[/tex]
= [tex]\frac{57}{1000}[/tex]
= .057
