CORRECT ANSWERS
◉ The company that manufactures the run3X running shoe wants to
test a new model of that shoe. A sample of 450 runners who will test
the new model is built by randomly selecting thirty 10K races across
the country and then choosing at random 15 runners in each of
those runs.
a. simple random sample
b. stratified random sample
c. multistage random sample
d. voluntary response sample
e. completely randomized design
f. randomized block design
g. matched pairs
h. anecdotal evidence. Answer: c
◉ The owner of a running shop wants to test the new model of the
run3X running shoe. The owner collects a sample of 48 runners.
Twenty-four of the runners are randomly assigned to test the old
model of the run3X shoe. The remaining 24 runners are assigned to
test the new model of the run3X shoe.
,a. simple random sample
b. stratified random sample
c. multistage random sample
d. voluntary response sample
e. completely randomized design
f. randomized block design
g. matched pairs
h. anecdotal evidence. Answer: e
◉ A shoe store wants to open a branch on Michigan Avenue in
Chicago. Two hundred randomly chosen Chicagoans are requested
to provide data on the number of pairs of shoes they buy per year.
a. simple random sample
b. stratified random sample
c. multistage random sample
d. voluntary response sample

f. randomized block design
g. matched pairs
h. anecdotal evidence. Answer: a
, ◉ A corporation conducted a study to examine the effect of regular
exercise on the productivity of their employees, and which of their 5
departments would benefit the most from an exercise program.
From an initial sample of 30 employees from each of their 5
departments, they randomly selected 15 from each group of 30 to
undertake a strict exercise regime. The remaining 15 employees in
each group were left to go about their lives normally.
The above study is best described as:
a. a matched pairs experiment
b. anecdotal evidence
c. an observational study
d. a completely randomised design experiment
e. a randomized block design experiment. Answer: e
◉ A study was conducted to help determine which of the top two
political parties the general population would prefer to vote for in
the up-coming election. In determining whom to include in the
sample, two stages were involved. At the first stage, a random
sample of 50 individuals was selected from each of the 20 regions in
the country and then pooled into a combined sample of 1,000. At the
second stage, these 1,000 individuals were divided into 5 income-
level groups, and a random sample of 50 from each group was
selected.
Select all of the statements regarding the sampling design in the
above scenario that are true:
a. The study does not involve a voluntary response.
