Multiple Choice

Which of the following is not a correct statement about the systematic random sample?

• A) This type of sample has the advantage of being usable even when we do not know the size of the frame and, thus, cannot label each elementary unit with a number.
• B) This type of sample is a subset of a frame, or of an associated population, chosen by taking separate censuses in a randomly chosen subset of geographically distinct clusters into which the frame or population is naturally divided.
• C) This type of sample is a subset of a frame, or of an associated population, chosen by randomly selecting one of the first k elements and then including every kth element hereafter until the desired sample size has been reached.
• D) This type of sample might be used by a quality inspector who wants to determine the percentage of defective units produced on an assembly line that never shuts down.
• E) Both "This type of sample is a subset of a frame, or of an associated population, chosen by taking separate censuses in a randomly chosen subset of geographically distinct clusters into which the frame or population is naturally divided" and "This type of sample is a subset of a frame, or of an associated population, chosen by randomly selecting one of the first k elements and then including every kth element hereafter until the desired sample size has been reached" are incorrect.
