to estimate the percentage of defects in a recent manufacturing batch, a quality - control manager selects every twentieth widget that comes off the assembly line, starting with the tenth, until he obtains a sample of sixty widgets. what type of sampling method is used? cluster systematic simple random convenience stratified

Answer

Brief Explanations:

Systematic sampling selects elements at regular intervals from an ordered population. Here, every twentieth widget starting with the tenth is chosen, which fits the definition of systematic sampling. Cluster sampling groups the population into clusters and selects entire clusters. Simple random sampling selects elements randomly without any pattern. Convenience sampling selects elements that are easily accessible. Stratified sampling divides the population into strata and samples from each stratum.
