A simple random sample was selected of large urban school districts
throughout New England. The selected districts were identified as
target districts. Within each district, a simple random sample of its
high schools was chosen and the principals of those high schools was
chosen and the principals of those high schools were interviewed.
Which of the following statements regarding this design is not true.
a.) This is an example of a multi-stage cluster sample
b.) Results from the interviews cannot be used to infer responses of
the population of interest
c.) The population of interest is the set of all high school principals in
New England
d.) Not every subset of principals has the same chance of selection
e.) All of these statements are true.

The student council of your high school wants to conduct a survey regarding the
dress code for school dances. You have advised them that it might be best to
conduct a stratified random sample of the student body. Which of the following is
not a valid stratified design? Assume the result of the separate samples will be
combined into a single sample of the student body.
a.) Two simple random samples are to be conducted: one of the boys in the student
body and the other of the girls in the student body.
b.) Four simple random samples are conducted: one in each of the four classes
c.) Two simple random samples are conducted in randomly selected homerooms:
one of the boys in the selected homerooms and the other of the girls in the selected
homerooms.
d.) Twoo random samples are conducted: one of students whose GPA’s are 2.5 or
higher and the other of students whose GPA’s are less than 2.5
e.) None of these statements is a valid design

21052 65031 45074 92846 67815 78231 01548
20235 56410 82713
Which of the following statements regarding this excerpt of the given
random digit table is true?
a.) this table can only be used for data coded with five-digit numbers
b.) In order to use this table for a population of 100 names, the names could
be coded 00-99; the random two-digit numbers would be selected to
identify chosen names
c.) It is critical to begin the selection of random digits at the beginning of
the list
d.) This table can only be used if the data labels include all of the digits in
the table.
e.) None of these statements are true.

stronger right hands than left hands. A sample of 10 right-handed persons is
selected randomly. Which of the following designs would be most appropriate
for this study?
a.) an observational study
b.) a design blocked for gender to determine if right-handed strength differs by
gender
c.) a repeated measures (matched pair where individual serves as their own
control) experiment in which each subject represents a block wherein the
strength of the right hand and the left hand is measured in random order.
d.) five of the subjects are randomly placed in the control group and the other
in the treatment group. All are tested and the results of each group are
compared.
