MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.
1) Determine whether the given description corresponds to an experiment or an observational 1)
study. A stock analyst selects a stock from a group of twenty for investment by choosing the
stock with the greatest earnings per share reported for the last quarter.
A) Experiment B) Observational study
2) Identify which type of sampling is used. The name of each contestant is written on a separate 2)
card, the cards are placed in a bag, and three names are picked from the bag.
TE
A) Simple Random
B) Cluster
C) Convenience
D) Stratified
E) Systematic
ST
3) Identify which type of sampling is used. To avoid working late, a quality control analyst 3)
simply inspects the first 100 items produced in a day.
A) Systematic
B) Stratified
C) Convenience
SO
D) Cluster
E) Simple Random
4) An education expert is researching teaching methods and wishes to interview teachers from a 4)
particular school district. She randomly selects ten schools from the district and interviews
all of the teachers at the selected schools. Does this sampling plan result in a random sample?
Simple random sample? Explain.
LU
A) No; no. The sample is not random because teachers in small schools are more likely
to be selected than teachers in larger schools. It is not a simple random sample
because some samples are not possible, such as a sample that includes teachers from
schools that were not selected.
B) Yes; yes. The sample is random because all teachers have the same chance of being
selected. It is a simple random sample because all samples have the same chance of
TI
being selected.
C) Yes; no. The sample is random because all teachers have the same chance of being
selected. It is not a simple random sample because some samples are not possible,
such as a sample that includes teachers from schools that were not selected.
O
D) No; yes. The sample is not random because teachers in small schools are more likely
to be selected than teachers in larger schools. It is a simple random sample because
all samples have the same chance of being selected.
N
5) Identify the type of observational study used. A town obtains current employment data by 5)
polling 10,000 of its citizens this month.
A) Prospective B) Retrospective C) Cross-sectional D) None of these
6) Determine whether the given value is a discrete or continuous variable. People are asked to 6)
state how many times in the last month they visited their family doctor.
A) Continuous B) Discrete
