Answer:

a) 0.118.

Explanation:

The computation of the UCL is shown below:

Given that

N = 100

<u>Sample    Sample size      Number of retests       fraction defective </u>

1                      100                     4                                0.04

2                     100                      11                               0.11

3                     100                      6                               0.06

4                     100                      10                              0.1

5                     100                     4                                0.04

6                     100                      6                              0.04

7                     100                      1                                0.01

8                     100                      6                               0.06

9                     100                      9                              0.09

10                   100                      11                               0.11

Total              1,000                   68

Now p is

= 68 ÷ 1000

= 0.068

Now the standard deviation is

= √p(1 - p) ÷ √n

= √0.068 × (1 - 0.068) ÷ √100

= 0.025

Now the UCL is

= p + z × standard deviation

= 0.068 + 2 × 0.025

= 0.118

Total income added 1,170
