Cmq 200 Module 1 Exam -Defense Acquisition University

Module 1 Exam 1) Which equation is used by DCMA to calculate the selection interval (k) when the lot size is represented by capital N and the sample size is represented by lowercase n? k = n / N k = N / (n+1) k = (N + 1) / n k = N / n 2) What is the effect on an Operating Characteristic (OC) curve as AQL increases with a constant acceptance number? The OC curve approaches the ideal shape. The OC curve flattens out. The OC curve stretches right. The OC curve stretches left. 3) How does stratified sampling differ from cluster sampling? Stratified sampling uses a larger total sample size than cluster sampling. Cluster sampling can have clusters of varying sizes; all strata must be the same size. All clusters are sampled, not all strata are sampled. Stratified sampling uses a smaller total sample size than cluster sampling.4) In the cluster sampling method, what is the effect of using a smaller number of clusters? Fewer clusters increase the precision of the inspection. Fewer clusters reduce the sample's representation of the population. Fewer clusters increase the sample's representation of the population. Fewer clusters decrease the probability of
