Hi All,
Currently on a distance learning HNC and I am not quite sure whether the question just wants me to answer 'yes' or give mathematical evidence. Part A answered, Part B not sure... Any help would be great!
2. The process for the production of an electrical device is suitable for inspection by variables. Production is inspected in lots of 150, at inspection level II, normal inspection with AQL = 2.5%. The maximum temperature of operation for the device is specified as 50 °C.
(a) Use TABLES 4 and 5 to find the sample code letter, the sample size and the acceptability constant.
Code letter H
Sample Size 10
Acceptability constant 1.41
(b) A sample is taken and the temperature measurements are as follows:
43 °C, 49 °C, 46 °C, 39 °C, 44 °C, 45 °C, 40 °C, 48 °C, 46 °C and 41 °C.
Determine whether the lot should be accepted.
