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.)

every subset of principals has the same chance of
selection e.) All of these statements are true.

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

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
