Question

The results of inspection of DNA samples taken over the past 10 days are given below. Sample size is 100.

Answer 1

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  =  $\frac{\sum no\; of \; effective \; in\; each\; day}{no\; of \; day \times n}$

                                               = $\frac{7 + 6 + 6 + 9 + 5 + 6 + 0 + 8 + 9 + 1}{10\times 100}$

                                               = $\frac{57}{1000}$

                                               = .057
