82. close shave which of two brands (x or y) of electric
razor shaves closer? researchers want to design and
carry out an experiment to answer this question using
50 adult male volunteers. here's one idea: have all
50 subjects shave the left sides of their faces with the
brand x razor and shave the right sides of their faces
with the brand y razor. then have each man decide
which razor gave the closer shave and compile the
results.
(a) identify any flaws you see in the proposed design for
this experiment
(b) describe how you would design the experiment.
explain how your design addresses each of the
problems you identified in part (a).
