Keno. 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).
Short Answer
Part (a) samples are: 39 03 28 58 59 09 36 52 24 78 23 68 73 17 62 14 77 42 20 51
Part (b) samples after using MINITAB:
37 33 2 65 22 25 30 76 26 55 78 71 10 51 12 2 21 5 48 17
Step by step solution
Part(a) Step 1. Given information.
The given statement is:
In keno, 20 balls are chosen at random from a pool of 80 balls numbered 1-80.
Part (a) Step 2. Obtain 20 random samples of two-digit number by using Table I in Appendix A.
20 balls are chosen at random from 80 balls numbered 1-80 in the game of keno, follow the below-given procedure:
- To select a random sample of 20 balls from a total of 80 balls. First of all, each ball must be assigned a number from 1 to 80.
- Then pick a number at random from the list.
- If any number exceeds 80, we simply discard it and continue our pick from the table.
- The required sample can be calculated using the random number table as follows:
- 39 03 28 58 59 09 36 52 24 78 23 68 73 17 62 14 77 42 20 51
Part (b) Use a random-number generator to solve part (a).
Given below is the result of samples produced by using MINITAB:
