Q

In cluster sampling, the researcher does not need the names of all the population members, however fewer sampling points make it less likely that the sample is representative.

21
Q

In this type of sampling method, the population is divided into subpopulations

A

Stratified sampling

22

T or f

A

False

25
Q

Which of the following statements is not true?

A. For sampling plans with different sample sizes and fixed lot size/acceptance number, increasing the sample size will give the OC Curve a steeper slope and will decrease Pa for all quality levels.

B. For sampling plans with different acceptance numbers and fixed lot size/sample size, decreasing the acceptance number will give the OC curve steeper slope and will decrease Pa for all quality levels.

C. For sampling plans with different sample sizes/acceptance numbers and fixed lot size, OC curve starts to approach the ideal OC curve when the sample size and acceptance umber decrease.

D. For sampling plans with different lot sizes and fixed sample size/ acceptance number, having a moderately large batch size has a small effect on the probability of acceptance.

A

C. For sampling plans with different sample sizes/acceptance numbers and fixed lot size, OC curve starts to approach the ideal OC curve when the sample size and acceptance umber decrease.
