Chapter 1 Test
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 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) Observational study B) Experiment
Objective: Exam A
2) Identify which type of sampling is used. The name of each contestant is written on a separate card, the cards are
LU
placed in a bag, and three names are picked from the bag.
A) Stratified
B) Simple Random
C) Convenience
D) Cluster
E) Systematic
XE
Objective: Exam A
3) Identify which type of sampling is used. To avoid working late, a quality control analyst simply inspects the first
100 items produced in a day.
A) Stratified
B) Simple Random
C) Convenience
LI
D) Systematic
E) Cluster
Objective: Exam A
BR
4) An education expert is researching teaching methods and wishes to interview teachers from a 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.
A) 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 being selected.
B) 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
AR
that were not selected.
C) 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.
D) 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.
Y
Objective: Exam A
5) Identify the type of observational study used. A town obtains current employment data by polling 10,000 of its
citizens this month.
A) Retrospective B) Cross-sectional C) Prospective D) None of these
Objective: Exam A
