The study considered 62 subjects: 40 healthy men and women and 22
suffering form colds or flu. Components in this study was the
formation of two groups of equal size from 62 particpants with each
group containg both health and sick participants
a: how could you take 40 healthy subjects and randomly divide into two
groups of equal size using a random-number table
B repeat part a for the 22 sick patients
CHow would you combine the groups of healthy and sick subjects to form
two equal size of both healthy and sick

Assign every person a random number. Most computer random number
generators generate a long number between 0 and 1 (a repitition is
almost impossible).
If you are not using a computer, roll dice 10 times for each person,
getting a ten-digit number with each digit from 1-6. That'll do fine.

Arrange in numerical order. The lowest half form group A, the rest group B.

> repeat part a for the 22 sick patients

Ditto.

Just put both group A's together, and both group B's, remembering who
was originally healthy and who was originally sick.
