A razorblade manufacturer wants to test responses to a new blade for heavy beards. What is the best sample for an experiment?


a random sample from all people of all ages

a random sample of men with beards

a random sample of all people who shave

a random sample of men who shave and have a heavy beard

Verified Answer :

The right answer would be A random sample of men who shave andn have heavy beard because the person should like to shave because you shouldn't force them to try it. They also need to have a heavy beard because the manufacturer is creating a razor blade for men with heavy beards. Hope this helps.
