In the game of keno, 20 balls are selected at random from 80 balls numbered 1-80. In Exercise 1.44 on page 15, you used simple random sampling to simulate one game of keno.
a. Use systematic random sampling to obtain a sample of 20 of the 80 balls.
b. Which method is easier: simple random sampling or systematic random sampling?
c. Does it seem reasonable to use systematic random sampling to simulate one game of keno? Explain your answer.

REFERECE 1.44

In the game of keno, 20 balls are selected at random from 80 balls numbered 1–80.

a. Use Table I in Appendix A to simulate one game of keno by obtaining 20 random numbers between 1 and 80. Start at the two-digit number in line number 5 and column numbers 31–32, read down the column, up the next, and so on.

b. If you have access to a random-number generator, use it to solve part (a).
