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).
